2-6-2T Prairie

The 2-6-2 represents the wheel arrangement of two leading wheels, six coupled driving wheels and two trailing wheels. This arrangement is commonly called a Prairie. The majority of American 2-6-2s were tender locomotives, but in Europe tank locomotives, described as 2-6-2T, were more common. The first 2-6-2 tender locomotives for a North American customer were built by Brooks Locomotive Works in 1900 for the Chicago, Burlington and Quincy Railroad, for use on the Midwestern prairies. The type was thus nicknamed the Prairie in North American practice. This name was often also used for British locomotives with this wheel arrangement.
As with the 2-10-2, the major problem with the 2-6-2 is that these engines have a symmetrical wheel layout, with the centre of gravity almost over the centre driving wheel. The reciprocation rods, when working near the centre of gravity, induce severe side-to-side nosing which results in intense instability if unrestrained either by a long wheelbase or by the leading and trailing trucks. Though some engines, like the Chicago and Great Western of 1903, had the connecting rod aligned onto the third driver, most examples were powered via the second driver and were prone to the nosing problem.

The ESU Full Throttle Steam files now include a few new logic features for added operational realism while still leaving you in control of HOW YOU wish to run your locomotive.
Heavy Load: F9 by default.
Similar to the “Drive Hold” button on the Full Throttle Diesel files “Heavy Load” allows you to adjust the “Steam Cut Off Valve” at any speed allowing for a fierce full chuff or drifting with snifters and rod clanks. Heavy load can also act as an offset allowing speed adjustments when engaged if desired.
Coast: F4 by default.
Opposite of “Heavy Load” Coast allows for a negative offset allow drifting sounds of Rods and snifter valves at any speed. You again have the option to hold the speed to adjust the speed with this offset active. Even allowing for an increase of speed with no chuffs as if drifting downhill.
Independent brake: F10 by default
Identical to the Full Throttle Diesel files. This allows for the locomotive to stop more quickly than its regular momentum would normally carry it. This one is pretty self-explanatory – just press the brake and come to a stop! For additional options there are 3 Braking rates that can be set up for user preference.
Articulation: Sound Slot 2
By adding Sound Slot 2 to the F8 Function Mapping and enabling the "Secondary Trigger" (CV250) you can add a second set of drivers making any ESU Steam File articulated.
Function Mappable Air Horn: F21 by default
Sound Slot 21.
Many Steam locomotives had a single chime airhorn equipped. Those modelling SP, MILW, and others can now have this feature and put it where they would like in the function mapping in addition to the whistle.

Southern Pacific 4449, also known as the Daylight, is the only surviving example of Southern Pacific Railroad's GS-4 class of steam locomotives and one of only two GS-class locomotives surviving, the other being GS-6 4460. The locomotive is a streamlined 4-8-4 "Northern"-type steam locomotive. GS is abbreviated from "Golden State", a nickname for California (where the locomotive was operated in regular service), or "General Service".
The locomotive was built by Lima Locomotive Works in Lima, Ohio, for SP in May 1941; it received the red-and-orange "Daylight" paint scheme for the passenger trains of the same name which it hauled for most of its service career. No. 4449 was retired from revenue service in 1956 and put into storage. In 1958, the SP donated the locomotive to the City of Portland, Oregon. The City then put the locomotive on static display in Oaks Amusement Park, where it remained until 1974.
The locomotive was then restored to operation for use in the American Freedom Train, which toured the 48 contiguous United States as part of the nation's 1976 Bicentennial celebration. The engine has operated in excursion service throughout that area since 1984.
The locomotive's operations are based at the Oregon Rail Heritage Center in Portland, Oregon, where it is maintained by a group of volunteers named the Friends of SP 4449. In 1983, a poll of Trains magazine readers selected 4449 as being the most popular locomotive in the nation.
This recording comes from SP 4449.

The K-27 is a class of 3 ft 0 in (914 mm) narrow gauge 2-8-2 steam locomotives built for the Denver and Rio Grande Railroad by the Baldwin Locomotive Works in 1903. Known by their nickname "Mudhens," they were the first and the most numerous of the four K classes of Rio Grande narrow gauge engines to be built. Of the original fleet of 15 locomotives, two survive to this day and operate on heritage railways in the United States.
Fifteen locomotives were built, originally class 125, they were reclassified as K-27s in 1924 when the Denver and Rio Grande became the Denver and Rio Grande Western Railroad. In the D&RGW's classification system, K was short for MiKado while 27 referred to the engine's 27,000 lbf of tractive effort. The K-27s were built as Vauclain compounds, with two cylinders on each side, expanding the steam once in the smaller cylinder and then a second time in the larger one. The extra maintenance costs of the two cylinders were greater than the fuel saving, so they were converted to simple expansion in 1907–1909. As a result, the K-27s were the Rio Grande's last purchase of compound locomotives. They were built with their main structural frames outside the driving wheels, with the counterweights and rods attached outside the frames.
They pulled freight, passenger and mixed trains on the D&RGW in and over the Colorado Rocky Mountains, traversing the entire length of the railroad. Many of them also spent time on the Rio Grande's subsidiary, the Rio Grande Southern. In later years, some were used as switchers at the D&RGW's yards in Durango, Gunnison, and Montrose.

The 2-8-2 wheel configuration on steam locomotives was one of the most highly used configurations made. This type of locomotive with 2 pilot wheels, 8 drive wheels, and 2 trailing wheels to support a larger firebox was first built for the Emperor of Japan, thus the name Mikado type. The first Mikado built for service in the US was built in 1901 and was owed by the Bismarck, Washburn and Great Falls until 1904 when it was acquired by the Soo Line.
This recording comes from the newer L-1 Class SOO Line 2-8-2 #1003. The SOO #1003 is a very average 2-8-2 not much different than the USRA light Mikado design. It does have slightly larger cylinders and a boiler pressure of about 170 PSI.
Originally delivered with a Westinghouse Cross Compound Air Pump, Walschaerts valve gear, an oil headlight, and a manual Johnson Bar, it was gradually upgraded to include a Power Reverse gear and electric headlights and class lights by about 1920.
It is important to note that wheel arrangement does very little to change the sounds of a steam locomotive. (Articulation aside). Boiler pressure, Stack size, Cylinder size and even the engineer at the throttle can all have more effect on the sound of locomotive than how many wheels are beneath it. While our dedication to accuracy is paramount, causing us to release very specific files, we will also be releasing some more generic files to try to give broad range to locomotives owned by MANY railroads. While this is a fairly common design and the sounds are similar to many locomotives, this ESU Full Throttle File is quite specific to the SOO #1003. We've included a few extra whistles for some variation.

UP 4-6-6-4 Challenger H0 N XL L M4
- Article numbers:S0556
- Last change: 4/2/2024
- Manufacturer: ESU
Equipped with ESU "FULL THROTTLE STEAM" features!
The name Challenger was given to steam locomotives with a 4-6-6-4 wheel arrangement. This means that they have four wheels in the leading "pilot" truck, which helps guide the locomotive into curves; two sets of six "driving" wheels, and finally, four "trailing" wheels, which support the rear of the engine and its massive firebox. Each set of driving wheels has its own steam cylinder. In essence, the result is two engines under one boiler.
The frame of the locomotive is "articulated," or hinged, to allow it to go through curves. When watching the approaching locomotive go through a curve, you can see the boiler swing out left or right independently of the lower half of the engine, as the rear half of the locomotive remains in a straight direction until its wheels and frame are halfway through the curve.
The Challengers were designed for fast freight service, but occasionally pulled passenger trains.
The ESU Full Throttle Steam files now include a few new logic features for added operational realism while still leaving you in control of HOW you wish to run your locomotive.
Heavy Load: F9 by default.
Similar to the “Drive Hold” button on the Full Throttle Diesel files “Heavy Load” allows you to adjust the “Steam Cut Off Valve” at any speed allowing for a fierce full chuff or drifting with snifters and rod clanks. Heavy load can also act as an offset allowing speed adjustments when engaged if desired.
Coast: F4 by default.
Opposite of “Heavy Load” Coast allows for a negative offset allow drifting sounds of Rods and snifter valves at any speed. You again have the option to hold the speed to adjust the speed with this offset active. Even allowing for an increase of speed with no chuffs as if drifting downhill.
Independent brake: F10 by default
Identical to the Full Throttle Diesel files this is a custom feature created by using logic inside sound slot 11. This allows for the locomotive to stop more quickly than its regular momentum would normally carry it. This one is pretty self-explanatory – just press the brake and come to a stop!
Articulation: Sound Slot 2
By adding Sound Slot 2 to the F8 Function Mapping you can add a second set of drivers making any ESU Steam File articulated.
Function Mappable Air Horn: F21 by default
Sound Slot 21.
Many Steam locomotives had a single chime airhorn equipped. Those modelling SP, MILW, and others can now have this feature and put it where they would like in the function mapping in addition to the whistle.

Equipped with ESU "FULL THROTTLE STEAM" features!
During the late 1930s, the Union Pacific often used helpers to move trains from Ogden to Wasatch. The UP wanted to simplify this move so they asked their "Department of Research and Mechanical Standards" (DoRMS) to design a locomotive that could pull a 3600 ton train unassisted over the 1.14% grade of the Wasatch.
The designers determined that to pull a 3600 ton train, a tractive effort of 135,000 lbs would be needed. Assuming a factor of adhesion of 4.0, the weight on drivers would have to be 4.0 * 135,000 = 540,000 lbs. Given an axle loading of 67,500 lbs each, this would require 8 drivers or an x-8-8-x wheel arrangement. The designers agreed upon the 4-8-8-4 design. Next, the horsepower and cylinder sizes were computed based on 300 psi boiler pressure. Although they weren't planning to pull these freight trains at 80 MPH, the DoRMS designed them for 80 MPH in order to have a sufficient factor of safety built into the design. What resulted is considered by many to be the most successful articulated steam locomotive ever built. 4000 was delivered to Omaha at 6PM, September 5, 1941.
The 25 Big Boys were built in two groups. The first group, called "class 1", were built starting in 1941. They were numbered 4000-4019. The second group, "class 2", were built in 1944. They were numbered 4020-4024. The last revenue freight pulled by a Big Boy was in July of 1959. Most were retired in 1961. The last one was retired in July of 1962. As late as September, 1962, there were still four operational Big Boys at Green River, WY.

The Shay locomotive was the most widely used geared steam locomotive. The locomotives were built to the patents of Ephraim Shay, who has been credited with the popularization of the concept of a geared steam locomotive.
Shay locomotives had regular fire-tube boilers offset to the left to provide space for, and counterbalance the weight of, a two or three cylinder "motor," mounted vertically on the right with longitudinal drive shafts extending fore and aft from the crankshaft at wheel axle height. These shafts had universal joints and square sliding prismatic joints to accommodate the swiveling trucks. Each axle was driven by a separate bevel gear, with no side rods.
The strength of these engines is that all wheels, including, in some engines, those under the tender, are driven so that all the weight develops tractive effort. A high ratio of piston strokes to wheel revolutions allowed them to run at partial slip, where a conventional rod engine would spin its drive wheels and burn rails, losing all traction.
Shay locomotives were often known as sidewinders or stemwinders for their side-mounted drive shafts. Most were built for use in the United States, but many were exported, to about thirty countries, either by Lima, or after they had reached the end of their usefulness in the US.

2-8-2 Heavy Mikado H0 N XL L M4
- Article numbers:S0514

- Manufacturer: ESU
The 2-8-2 wheel configuration on steam locomotives was one of the most highly used configurations made. This type of locomotive with 2 pilot wheels, 8 drive wheels, and 2 trailing wheels to support a larger firebox was first built for the Emperor of Japan, thus the name Mikado type. The first Mikado built for service in the US was built in 1901 and was owed by the Bismarck, Washburn and Great Falls until 1904 when it was acquired by the Soo Line.
The USRA Heavy Mikado was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration (USRA), the nationalized railroad system in the United States during World War I. These locomotives were of 2-8-2 wheel arrangement in the Whyte notation, or 1′D1′ in UIC classification. A total of 233 locomotives were built to this plan for the USRA; postwar, it became a de facto standard design, which was built to the total of 957 locomotives including the USRA originals and all subsequent copies.
Heavy Mikado used the same running gear as the USRA Light Mikado but were built to a higher axle load, larger cylinders and a much larger boiler for more power and steam-generating ability. Many aspects of the PRR L1s class were carried over to the Heavy Mikado, although not that locomotive's distinctive Belpaire firebox
