Equipped with ESU "FULL THROTTLE STEAM" features!
MUST use LokProgrammer Version 4.5.1 or newer.
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.
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.
Grade Crossing: Sequence. F22 by default.
Allowing 1 button push to play a “pre made” grade crossing cycles with variable lengths and whistle play.
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.

This LokSound V4.0 XL is customized for the Bachmann Shay. This sound file has 5 Whistles, which can be changed by setting CV48 to a value between 0 and 4.
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. Hide description more…
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.
