## The American Transition (US) Set

#### A new train set for TTDPatch

#### Developed by TT-Forums members

#### March 2008

#### Public release; version 0.87.3

### What is the "American Transition" set?

It´s the first regional train set for Transport Tycoon Deluxe working under TTDPatch that depicts American railroading. It´s a set of vehicles originating from the great American locomotive manufacturers and railroads, covering the period of the transition from steam to diesel (hence the name) and extending into the modern era.

The American Transition set starts in the year 1920, the earliest possible year under TTDPatch.

Two sets of American town names, both real-life and American style, are also included.

### Why an American set?

The United States has historically had the most extensive and diverse rail network found anywhere in the world, although it has decayed somewhat in recent years. Particularly at the height of the steam era, American railroads were second to none in speed, performance, and style. Even today, while passenger railroading is limited to commuter and the somewhat-erratic Amtrak national system, heavy-freight railroading is alive and well with quantities of cargo moved that dwarf most other systems.

### Who drew the whole set?

The American Transition Set was developed by an international team of members of the Transport Tycoon Forums (administered by Owen Rudge) and includes some elements previously developed by others. If you believe your work has been used and you are not properly credited, please post your concern in the forum for immediate attention. Second-hand complaints will be disregarded; specific complaints with evidence will be rectified as soon as possible. Please bear in mind that the TTD vehicle sprites are very small, and as such there is unavoidable similarity between similar vehicles.
If you wish to comment on the released set, please use the "US Train Set released [version x]" topic; if you want to contribute to development (note that this does not include feature requests) then use the "US Set Development Thread" topic.

### What TTD climate is it for?

The United States has a wide variety of geographical and climatic diversity. As a result, all of the environments in TTD (except Toyland) would be found somewhere in the United States, and in fact the various locomotives in the set were often best known in one particular area, e.g. the mountains, the desert, etc. Thus, the American Transition set is designed to be used in ALL three environments (temperate, arctic and sub-tropical), and provides traincars suitable for all available cargoes.

If you would prefer not to use the American Transition set in one or two of these climates, you can do so using parameters, details of which are given later in this document.

### How to install the American Transition Set

#### Configuring newgrf[w].cfg

The American Transition set is available in a DOS version ("usset.grf") and a Windows version ("ussetw.grf"). Simply copy the grf file into the "newgrf" directory under your TTD main directory and add the entry "newgrf/usset[w].grf" (with the "w" if you are using the Windows version of TTD) to your "newgrf[w].cfg" file.

You´ll need TTDPatch version 2.0.1 alpha 66 (or higher) to run this version. This is because there are many new features, including the new articulated engines feature, which are available only since TTDPatch 2.0.1 alpha 66. You can get the latest alpha version from http://www.ttdpatch.net/src/ if you don't have it already.

If you intend to use George's Extended Cargo Set (ECS), then you must include the file "usset-ecs-adapter.grf" in your newgrf folder and list it in newgrf[w].cfg after the usset GRF file.

Because this set is designed to be used in all available environments and comes with its own freight cars, it cannot coexist with any other train set. All other train sets should be deactivated in a US Set game using the GRF Status Window.

GRF files relating to other vehicles such as ships, road vehicles, and aircraft, as well as stations and other modifications, will not be affected or harmed by the usset[w].grf file. In fact, it is recommended that you include George's Long Vehicles, Michael Blunck's new ships, the most recent version of the Planeset and Michael Blunck's waypoint stations to provide a comprehensive selection of all vehicle types (as well as the US Stations and Industrial Stations Sets). If you do not already have these files, they are available from the Patch site or the TT Forums, links given at the end of this document. You might also want to include Michael Blunck's Cargoset to give you extra road vehicles for some cargos, but please see the detailed instructions later in this document

#### Supplying parameters to the American Transition set

The American Transition set currently supports six options. Simply add up the "value" numbers and put them after the "newgrf/usset[w].grf" line in your newgrf.cfg file, for example "newgrf/usset.grf 65" to reduce passenger and mail loading rates and disable the grade crossings.

- Parameter bit 0 (value 1) will deactivate the American grade crossings included with the set, in case you have another roadset installed.
- Parameter bit 1 (value 2) will deactivate the set in the temperate climate.
- Parameter bit 2 (value 4) will deactivate the set in the arctic climate.
- Parameter bit 3 (value 8) will deactivate the set in the sub-tropical climate.
- Parameter bit 4 (value 16) will give consistent boxcars for the same cargo. Normally, American trains, even carrying the same cargo, will have wildly different styles and liveries of traincars, which in this set is provided by random graphics; this parameter disables the randomizing function, so the same car type and cargo will always have the same appearance, as in original TTD.
- Parameter bit 5 (value 32) will change the behaviour of the Acela Express and HSE 'Sunset' trains slightly so that the AI can use them more effectively.
- Parameter bit 6 (value 64) will change passenger and mail loading rates to 10 of each per tick.
- Parameter bit 7 (value 128) will remove the length restriction of 8 cars (including the engine) for multiple units.

In the majority of cases, no parameters or bit 1 only (set in order to coexist with the DB Set ["newgrf/usset[w].grf 2"]) will be appropriate.

#### Example newgrf[w].cfg configurations

This section intends to give you possible advice on how to set up your newgrf[w].cfg in order to avoid causing any conflicts between sets.
There are now a range of train sets available for TTDPatch so you are advised to use common sense and deactivate all other train sets in a US Set game. The US Set uses almost all available IDs so cannot coexist with (for example) the DB Set. Please use the GRF Status Window available in game to put a red flag next to other train GRFs and a green flag next to the "US Train Set" GRF. A selection of example scenarios is included below.

Scenario 1: Using the US Set in all three climates but including the Cargoset for its extra road vehicles.
`newgrf/cargoset[w].grf
newgrf/usset[w].grf`

(Note that the Cargoset is before the US Set in the list.)

Scenario 2: Using the US Set in all three climates, the Cargoset for its extra road vehicles but omitting the level crossings because you are using an alternative roadset.

`newgrf/cargoset[w].grf
newgrf/usset[w].grf 1`

Scenario 3: Using the US Set in tropical and arctic climates only with the DB Set XL in temperate and the Cargoset for its extra road vehicles.

`newgrf/cargoset[w].grf
newgrf/dbsetxl[w].grf
` `newgrf/usset[w].grf 2`

Scenario 4: Using the US Set in all climates but retaining the use of other sets for saved games using them.

`newgrf/dbset[w].grf !
` `
` `newgrf/cargoset[w].grf
newgrf/usset[w].grf
newgrf/dbsetxl[w].grf !
newgrf/tropicset[w].grf !`

Please post on the forums if you need any assistance with this matter.

To summarise:

- The US Set no longer deactivates other train sets and you should ensure before starting a game that only the required sets are activated.
- Ensure that the Cargoset is before the US Set if you want its road vehicles to be available without causing problems for the US Set.
- Sets you do not intend to use by default should have an exclamation mark after their filename in newgrf.cfg.

#### Variables to set in ttdpatch.cfg

You need to set the following variables in your ttdpatch.cfg file:

- newtrains on - mandatory
- electrifiedrailway on - mandatory. The US has an extensive electrified rail system (the Northeast Corridor) that historically handled both freight and passengers, as well as other shorter systems in mountains and tunnels.
- unifiedmaglev 1 - mandatory. Although this set does not offer maglevs at this time, the monorail and maglev systems need to be combined to leave the way open for the electrified rail.
- startyear 1921 - very important because there are many interesting locomotives (including the steamers) in the early years which you´ll miss when starting too late.
- multihead 0 - very important. This is needed to get the original engine specifications, e.g. using multple-engine traction gives you increased power but won´t increase speed, as it is in reality.
- tracktypecostdiff on - very important. Electrified tracks are more expensive than normal tracks, especially in America!
- semaphores on - very important. The steaming age needs semaphores! An American-style signals set, including American semaphores, is currently available on the US Set website.
- mammothtrains on - strongly recommended. Why would you want to use a US set if you only used short trains?
- largestations on - strongly recommended to get the full benefits from the above.
- enginespersist off - strongly recommended because there are so many engines following one another that you shouldn't stick to an early choice for many years. There are many favourable engines in the set! In addition, the lack of suitable new motive power during certain years was a real operational problem for American railroads.
- wagonspeedlimits on - strongly recommended for the realism and the challenge of keeping both slow and fast trains running together.
- signalsontrafficside on - recommended to get the right types of signals
- gradualloading on - recommended to see gradual loading and unloading of some carriages.
- freighttrains 5 or freighttrains 3 - very important - depending on your preference. This is crucial to make freight trains as heavy as they are in real life. Then you will need lots of locomotive power to pull them! For flat terrain you will probably prefer "freighttrains 5" and for extremely mountainous terrain "freighttrains 3" (unless you want a real challenge!).
- higherbridges on - recommended to help your freight trains high in the mountains by staying at a constant level.

You should also enable the "realistic model" of train acceleration to get full benefit from the different engines in the set, i.e. you should include in your ttdpatch.cfg file the lines: (x and y are for monorails/maglevs and road vehicles and should be set to a value of 0 to 3.)

curves 33[xy]

### Special locomotives

#### Articulated locomotives

Some locomotives in the set were articulated or extremely long and have been implemented in the US Set as double-headed engines (although you will only notice this on corners). Therefore, the "multihead" switch must be set to "multihead 0" and not "multihead 30" or any other value to give the correct power values.

The long steam engines that work in this way are:

- Cab-Forward AC-6 (2 parts plus tender)
- Class 3900 'Challenger' (2 parts plus tender)
- Class 4000 'Big Boy' (2 parts plus tender)
- H8 'Allegheny' (2 parts plus tender)
- N&W Y6b (2 parts plus one tender in early years or two tenders in later years)

Other articulated engines are:

- EP-2 'Bipolar' (2 parts)
- EP-4 'Little Joe' (2 parts)
- DDA40X 'Centennial' (2 parts)
- GE 'Big Blow' Turbine (2 parts plus tender)

The locomotives with tenders have multiple visually different parts. The appearance is determined by their position in the train. The first of each set of the engine will be the front part.

As of version 0.82 of the set, the complete engines, and their associated tenders if relevant, will be automatically purchased with the initial purchase in the vehicle list, and for each additional locomotive purchased.

#### Dual-headed engines

There are also some normal dual headed engines that will be bought initially as two pieces. They should be split up, with the carriages in the middle: one head should be at each end of the train.

These trains are:

- TurboTrain
- Acela Express
- JetTrain. The JetTrain does not require both locomotives: it can be operated with one locomotive only or with one at each end, as desired. A streamlined end car is provided for the cases when only one engine is used. Please note that, as of TTDPatch 2.0.1 Alpha 30, the JetTrain will be purchased as one complete piece, with both heads included, but you can still sell one of these to halve the purchase and running costs.
- HSE-10 'Sunset'

With parameter 5 enabled, the last car of the Acela Express and the HSE-10 'Sunset' becomes a streamlined end car if the second engine is not bought. It is therefore possible to use them as double- or single-headed engines with their matching liveries. The AI will also be able to use them in more cases with this parameter.
In the train purchase table it will therefore appear with this parameter that the Acela Express and HSE-10 'Sunset' are half the price of comparative locos; this is not the case because it is the price per head, not for the two combined as it usually is for double-headed locomotives.

#### DMUs

This set includes several DMUs.

The Doodlebug DMU is actually a normal train that pulls heavyweight coaches, and has a capacity of its own. Normal coaches placed behind it in a train do not provide additional power.

The Budd RDC DMU emulates a modern DMU in that all wheels are powered. Using the latest patch, purchasing a locomotive of this type will actually cause any mail or passenger cars in the train to take on the same horsepower rating of the locomotive itself. The effect is that the performance of the train is not affected by its length, since all cars contribute power. This does not work with freight cars as freight is not transported using DMUs. Bi-level passenger cars do not exhibit this feature either, since Budd RDCs were designed long before bi-level cars.

There is also a series of more modern DMUs, which are designed to pull unpowered cars. These DMUs have a capacity of people, but do NOT cause trailing cars to take on their power. One of these DMUs can pull two other similar cars; for a longer train, you will want to add additional DMUs as multiheaded engines. Although the following cars use livery overrides to take on the appearance of the DMU, they are not actually powered; this reflects their design in the real world. In addition, they are intended for commuter service, and thus have no matching livery for mail or other cars, although of course they can pull them in the train. Note that both DMUs will give a livery override to both normal and bi-level passenger cars in a train.

- Colorado DMU
- Colorado Bi-Level DMU

#### EMUs

The set offers several EMUs. These represent electric multiple-units in which all wheels are powered. Using the latest patch, purchasing a locomotive of this type will actually cause any mail or passenger cars in the train to take on the same horsepower rating of the locomotive itself. The effect is that the performance of the train is not affected by its length, since all cars contribute power. This does not work with freight cars as freight is not transported using EMUs.

For appearance, you will want to purchase one EMU locomotive to head the train, followed by passenger cars as long as you wish. However, both of these trains are passenger-only commuter trains and, as such, are not designed to pull mail cars (although of course they can)..

- MP-54
- Budd 'Cosmopolitan' M-2

#### Diesel booster ("B") units

When diesel locomotives were first offered for sale, the engines were too large to get enough power into one "piece"; therefore, they were offered as A (with-cab) and B (cabless) units, which would be combined as needed to provide enough power for any given train. Aside from the requirement of a cab in front, these could be combined in any combination.

The US set reflects this practice by automatically converting a chain of similar multiheaded locomotives into A and B units. This is done in the following pattern:

<AXXXXX
<ABXXXXX
<ABBXXXXX
<ABBA>XXXXX
<ABBBA>XXXXX

and so on. The following diesel locomotives exhibit A and B units:

- EMD F7
- Alco P series
- EMD E8
- Baldwin RF16 'Sharknose'

Of course, the additional units must be purchased with the <ctrl> key held down.

#### Tenders

All American steam locomotives included in this set, of all types, and the Big Blow Turbine require a tender. These have an automatic livery override to make them correct for the engine that is pulling them. These tenders are automatically purchased with the engine from version 0.82 onwards.

Note: Because of limitations with livery overrides, all tenders in a train will match the lead locomotive, even if they are actually immediately behind a loco of a different type. Thus, you should not multihead steam locomotives of different types, or at least not wildly different types.

#### Restrictions on wagon attachment

Certain trains in the set have restricted wagon capabilities. This is because they are either not appropriate or not designed for hauling certain wagons. Locomotives that exhibit this functionality are:

- Zephyr - can only haul passengers, mail and valuables.
- Hiawatha - can only haul passengers, mail and valuables.
- UAC TurboTrain - can only haul passengers and mail and not bi-level passenger cars.
- E60CP - can only haul passengers, mail, valuables, food and goods.
- AEM7 - can only haul passengers, mail, valuables, food and goods.
- Acela Express - can only haul passengers and mail and not bi-level passenger cars.
- JetTrain - can only haul passengers and mail and not bi-level passenger cars.
- HSE-10 'Sunset' - can only haul passengers and mail.

### Playing the American Transition Set

As well as using the aforementioned "special engines" correctly, it is important to note several other points about the American Transition Set.

#### Cabooses and ETDs

With few exceptions, American railroads are not and never have been constructed to the standard of many European rights-of-way. American mainlines, to say nothing of branch lines, are generally full of curves and hills, rarely double-tracked, and closely surrounded by trees except in the plains and desert. Combined with the great length of many American freight trains, often the engineer would not be able to see the rear of his train to make sure it was still attached. Consequently, the caboose was developed. The conductor of the freight train would ride in the caboose at the rear of the train, doing paperwork and perhaps offering meals to the brakemen or other train staff. Every American freight train up until 1960 should be equipped with a caboose at the rear.

After 1960, with improvements in air-brakes and radio communications technology, the need for a crew member to be at the rear of the train diminished. As the railroads were financially in tough straits at this time, the caboose slowly vanished from the rails, replaced by a simple ETD (End of Train Device), which is basically a high-powered red lantern attached to the rear coupler on the train. The ETD is offered as a separate, very very short traincar, and should be placed at the rear of all post-1960 new freight trains.

Because the cabooses had already been long since paid for, some have stayed around long after 1960, simply becoming older and more decrepit, even occasionally appearing on a train today. Thus, trains already equipped with cabooses in 1960 may keep them, at least until their next locomotive replacement.

No passenger train should have either a caboose or an ETD. All the passenger car sets are equipped either with a special observation end-car, or rear taillights, as in reality. A mixed train would not require a caboose if the passenger cars were at the rear of the train, but would have one if the passenger cars were at the front of the train, followed by freight cars.

If you are having trouble moving the ETD around in the depot window, please click and drag to the right of where it appears to be. The ETD's positioning is unusual because it is supposed to be actually fastened to the rear of the last car. Being such a short vehicle, it is not unlikely that there is a bug with it. Please report any such bugs in the forums.

#### The American Transition Set and the AI

This set is most useful for those of you who like to play without the rubbish AI. While in reality there were a great many railroads in the U.S., most of them were better at route design than the AI is. Additionally, the AI can't figure out how to handle the multi-part locomotives, and tries to either use them with one part, or put the two parts at opposite ends of the train where they usually don't belong. Certainly the AI never uses a caboose, or an ETD (because putting them on the end of a train is impossible with the current patch features).

The AI handling has been improved in version 0.85 of the set so that the AI uses the full range of locomotives, wagons and track types, but this will be further refined in future versions of the set.

If you do decide to play using the AI with the US set, you may wish to turn on the parameter that helps it better handle the Acela Express and Sunset trains (parameter 5; value 32).

#### The American Transition Set and vehicle.dat

Because a vehicle.dat file will be loaded by TTD after the names in the usset[w].grf file have been processed, those custom names will overwrite the set´s engine names.

Therefore you should remove or rename an old vehicle.dat file in TTD´s directory or switch "vehicle names" to "default" in Game Options.

#### Random Liveries

The United States has had so many different railroad companies with so many different liveries that there are literally hundreds of different potential liveries that might have been seen over the years, and many dozens even today. Also, because modern American freight railroads generally do not spend much money on unnecessary expenses, it would be perfectly normal to see freight cars and locomotives from many predecessor companies, or rolling stock purchased used, or equipment on lease from who-knows-where, all in the same train. To achieve the same effect, all the freight cars are automatically generated in a wide variety of random liveries, including different colours, different designs, and other variances. It would be normal to find a freight train in which no two freight cars were alike. Some diesel freight locomotives also have several different liveries that might appear randomly upon purchase; this is equally normal. This prototypical behavior can be turned off using the parameters given above.

#### Metra Liveries

Passenger trains, on the other hand, would generally NOT have locomotives from different companies, although they might have mismatched cars (some steel, some Amfleet, for example.)

There are several passenger locomotives which are offered in both Amtrak livery, and in Metra livery, which is the commuter rail service around Chicago.
These are:

- E8
- F40PH2
- F59PHI

When you purchase a lead locomotive of one of these types, it will randomly appear in either Amtrak or Metra livery. Any additional multiheaded locomotives added to the train will be in the same livery, as will any bi-level cars. (Metra doesn't operate single-level cars or mail cars.) If you buy a locomotive, and you wanted one in the other livery from what you got, just keep buying them until you get the right kind, then throw away the others for a full refund.

The F59PHI is only offered in Metra livery in Temperate and Arctic climates to reflect the nature of Chicago's climate. The Amtrak California livery is only available in the sub-tropical climate.

#### Matching Liveries

In the 1930s-1950s, there were several famous "named" passenger trains, which had their own distinct liveries, train sets, and locomotives. These are represented in this set as follows:

- Broadway Limited: The Pennsylvania Railroad's GG1 electric locomotive pulled a train of Pullman cars in matching Tuscan red livery, with a streamlined observation car at the rear. Mail and passenger cars receive a livery override behind the GG1 from its introduction to 1960; the streamlined observation car appears if the last car in the train is a passenger car, as it should be.
- 20th Century Limited: The New York Central's crack service between New York and Chicago had an express Hudson locomotive with Art Deco streamlining designed by Henry Dreyfuss. Matching livery is provided for mail and passenger cars, again with a streamlined observation car at the rear. This livery is only available in the Temperate climate after 1938, with a non-streamlined Hudson available at other times.
- Hiawatha: The Chicago, Milwaukee, St. Paul and Pacific Railroad offered a high-speed commuter service between Chicago and Milwaukee, a distance of less than 200 miles. As the trains were not long, the Hiawatha was geared for extremely high speeds, not power. Matching livery is provided for mail and passenger cars, with a unique streamlined observation car at the rear.
- Daylight: The Southern Pacific Railroad had a long-haul passenger train through the Southwestern deserts. With its powerful Northern locomotive and "Daylight" color scheme, this train is considered to be one of the most beautiful trains of all time, and still runs on occasion with a restored and fully operational steam locomotive. Matching livery is provided for mail and passenger cars, with a streamlined observation car at the rear. In addition, if your train is long enough, it will include a special domed observation car.
- Olympian Hiawatha: In later years, the Hiawatha service was extended through the Rocky Mountains to Seattle. In the Rockies, the CMStP&P had electrification, and the train was hauled by the "Little Joe" electric locomotives. So Little Joes pull a passenger train very much in appearance to the normal Hiawathas, but with a special "Skytop" observation car at the end.
- UP "armour yellow" passenger livery: As stainless steel passenger cars were becoming standard in the 1950s, the Union Pacific wished to differentiate theirs in some way; so they painted them yellow with red stripes. The pre-Amtrak E8 locomotive appears in this livery (but not in the Arctic climate), and pulls matching mail and passenger carriages. (The 'Big Blow' turbine also shares this livery, even though it was much too loud to be used in passenger service.)
- GN "Empire Builder": The Great Northern Railway was conceived and built by a Canadian named James J. Hill, one of the great railroad tycoons of the past century. He earned the nickname "The Empire Builder", and the GN's flagship train was named in his honour. The bright green S2 Northerns were a common sight on this train, in the early years, with pullman green coaches behind.
  In the 1950s, a new streamlined train was built complete with dome cars, sleepers and matching E8s. The Empire Builder is currently operated by Amtrak and you can still travel the same route as the original "Empire Builder"

Several more modern trains have matching liveries as well, but this is more because they operate as train sets than because of any sense of style. These include the following:

- TurboTrain
- Acela Express
- JetTrain
- HSE-10 'Sunset'

Lastly, mail or passenger cars attached to a DMU- or EMU-powered train will take on the appearance of the lead MU.

#### Wagon speed limits

All wagons in the set except the passenger car, mail car and valuables car have speed limits intended to simulate their maximum speed in real life, enabled by the use of the "wagonspeedlimits" feature. It is strongly recommended that you use this feature for added realism and a greater gameplay challenge.

Please note that engines with a livery override for certain wagons automatically remove the speed limit for these wagons; this means that both the HSE-10 'Sunset' and the Colorado Bi-Level DMU can travel at their full quoted speed, even when hauling bi-levels.

#### Michael Blunck's NewCargo Set

The US Set (from version 0.86) supports Michael Blunck's NewCargo Set (version 0.12 at the time of writing). The following vehicles carry the "new cargoes":

- Boxcar: carries beer, fish and food.
- Reefer: carries fish and food.
- Gondola: carries beer and food.
- RoadRailer: carries beer, fish and food.

However, this support is not currently working.

#### Other New Cargo sets

Version 0.87 includes preliminary general new cargo support. This is still in an experimental stage but is believed to give acceptable results with many of the simpler new cargo schemes (as well as with original TTD). Please report any bugs in the forums.

### What vehicles make up the set?

There are a huge number of vehicles in this set. The following tables give the details of each type of locomotive and wagon.

The US Set is a 'full set', containing 68 different locomotives, many with livery overrides for passenger and mail carriages, and 27 different types of wagons, many with various designs. The US uses a wide variety of railroad stock and this set attempts to recreate at least a portion of this.

Many special features of TTDPatch are used to pay very close attention to detail, in particular livery overrides to change the appearance of wagons following a certain engine, variational graphics to change sprites based on a huge range of factors, wagon refitting for various cargos, tractive effort, callbacks and various other advanced features.

Notes:
1 U = Universal, P = Passenger, F = Freight, P/EF = Passengers and Express Freight, DMU = Diesel train set, EMU = Electric train set
2 Reliability: lower numbers are better.
3 Acela Express and Sunset can be used with one engine if parameter 5 is on.
4 Some of the Sunset's power is provided by two power (passenger) cars (one at each end of the train) unless parameter 5 is on.
5 This is the year of "early retirement" from which no more vehicles of this design can be purchased; may vary by several years due to game randomness.
6 Climates in which the locomotive is available: T = temperate, A = arctic, S = sub-tropical. Blank means all climates.

1 Limited lifespans.
2 Designed for use with Wooden Interurban only.
3 Tankers built from 1980 onwards travel at 75 mph / 120 kph.

4 Reefers built from 1966 onwards travel at 100 mph / 160 kph; the High-Cube refit (available from 1976) travels at 80 mph / 128 kph.

The table below summarises the refitting possibilities for each wagon. Obviously the availability of the cargo types depends on the climate being played.

Wagons can be refitted to the cargos shown in the table above but train refitting is only available at a consist level. Therefore the refitting list will display all the possible cargos that at least some wagons in the train can be refitted to. If you wish to refit only some wagons to a specific cargo, you should first remove them from the train before carrying out the refitting. Obviously, if one type of wagon in the train cannot be refitted to a certain cargo then it will not be refitted that way if you choose it in the list.

### Tractive Effort

The newer versions of the Patch support a much more realistic way of modeling locomotive power. Original TTD measured power simply by a horsepower rating. The full horsepower was assumed to be available at all times, and all speeds.
In reality, locomotive dynamics are rather more complicated, because steel wheels on steel wheels do not offer that much friction and hence traction. The weight of the locomotive that's on the driving wheels has a major influence on the effective ability of the locomotive to transfer its power to the track. It doesn't matter how much HP a loco has if it's just spinning its wheels because the train is too heavy; and steam locomotives in particular are very subject to this problem.
The Tractive Effort parameter takes this into consideration. It is displayed in the New Vehicle Purchase window, and has a major effect on vehicle performance, much more so than the horsepower. A freight locomotive has to have a fairly large tractive effort in order to get the train started at all. To reach a high speed, a high horsepower is nice, but the TE is really more important. For passenger trains, which are lighter, the TE is less important and the HP more, because the HP affects the maximum speed the train can reach.
TE is particularly important if the train needs to climb mountains, and essential if the train will have to start from a full stop on a mountain. If the train starts up a mountain going at full speed, the momentum it has already acquired will help it up the hill; but if the train has to start up the hill from a dead stop, it's all based on the TE of the loco.
That is why some locomotives with very high horsepowers do poorly in freight service, and other with low HP do well. The Mikado is a prime example of this. It has a comparatively low HP, but comparatively high TE. Thus it makes a good freight locomotive.
The US set is designed for realism in both tractive effort and horsepower. Each locomotive has its niche, and to find it, you need to carefully consider the tractive effort as well as the other parameters.

### Future plans

Many developments have been proposed, including:

- Completing newcargo support.
- Adding a full range of Alaska engines.
- Adding more loading states for freight cars.
- American buildings.
- American road systems (striping patterns).
- An American-liveried maglev, such as is planned for LA-Las Vegas and Baltimore-Washington DC.
- More random liveries for diesel locomotives and freight cars.
- Additional trains.
- Removing certain locomotives from certain climates to slightly reduce the available selection and to increase realism.

Other suggestions or contributions may be made in the Forums.

### Known bugs

- Running costs are identical for Low, Medium and High TTD running cost settings. This is a consequence of making this set financially challenging to play. The running costs are affected by the Construction Cost setting in Difficulty Settings. Due to improvements to TTDPatch, however, this will be fixed in a future version.
- nfo file is not encoded in the most memory-efficient format: will be fixed on an ongoing basis.
- Newcargo support is not complete.
- E8 loco is mistakenly labeled as 8
- GRF Date mistakenly displayed 07 when it should be 08

### History and bug fixes

0.87.4d:

- Fixed bug with reefers not being able to be refit.

0.87.3:

- Fixed bug with boxcars not being able to be refit.
- Added ECS compatibility - must put usset-ecs-adapter.grf afterwards.

0.87.2:

- Fixed bug with reefer callback 36 not checking properties correctly.

0.87.1:

- Fixed tropic cargo translation table being an action C rather than an action 0.
- Tried to fix gondola refit masks.

0.87:

- Now needs 2.0.1 alpha 66 or more recent.
- Added animated versions of Mikado, Mountain and GS-4 Daylight.
- Tried to improve the coding of some sections, shouldn't really be noticeable.
- Enabled Hudson in temperate.
- Added new SD40-2 livery in Arctic only and updated the previous liveries with new sprites.
- Added MBTA GP9 in temperate only.
- Updated F59PHI, F40PH-2 and F40C (livery of F40PH-2) Metra sprites.
- Updated Metra bi-level cars sprites.

- Added brief description of usage of each engine to in-game purchase window.
- Corrected some usage mistakes in the readme (although there are probably some remaining).

- Tankers built from 1980 onwards can travel at 75 mph in TTDPatch 2.5 beta 6 upwards.
- Fixed some noticeable colour randomising bugs with intermodals - you might now have to rebuild them to get a decent mix of colours though.
- Added some newcargos support - hopefully works with Pikka's Basic Industries & some of ECS but is not perfect - NewCargos support also seems to be broken.
- C&NW passenger trains now don't always have an observation car.
- Added C628 diesel into temperate climate only.
- Added Amtrak AmCafe and Viewliner passenger cars (latter as refit).
- Made interurbans available in sub-tropical climate.
- Updated open autorack sprites - open autoracks now travel at 70 mph, closed autoracks still at 80 mph.
- Completely reworked reefers, with updated sprites, speed changing from 90 to 100 mph in 1976, and a High-Cube refit from 1976 with larger capacity but slower speed.
- Added Alaska RR GP38-2 and SD70MAC in Arctic climate with matching passenger & mail cars, and even a matching caboose!
- Probably some other small changes that I didn't write down...

The US style grade crossings were drawn completely from scratch by nilsi to the design of the original Microprose sprites.

Coding and compilation of all vehicles was carried out by Oracle. (Thanks go to DaleStan for advice on coding the animated Berkshire and with other matters.) onodera coded the ECS compatibility.

Some elements of Michael Blunck's Arcticset may remain in the graphics and the file encoding. These were all taken from the GPLed version of the Arcticset and as such can freely be used in this set. These elements remain the copyright of Michael Blunck.
