Heisler N XL L M4

The Heisler locomotive was the last variant of the three major types of geared steam locomotives.

Charles L. Heisler received a patent for the design in 1892, following the construction of a prototype in 1891. Somewhat similar to a Climax locomotive, Heisler's design featured two cylinders canted inwards at a 45-degree angle to form a 'V-twin' arrangement. Power then went to a longitudinal drive shaft in the center of the frame that drove the outboard axle on each powered truck through bevel more…

Responding to user feedback this file uses "Standard North American Function Mapping".

This is a template used for all steam files from ESU LLC.
While we realize most Australian Locomotives do not use Bells or Air Horns they are included in the mapping due to the template used. This is easily changable so the user can set the function mapping work as desired.

N&W Class Y6B 2-8-8-2 N XL L M4

The Norfolk and Western Class Y6b was a class of 2-8-8-2 Mallets built between 1948-1952 with a total of 30 examples built for the Norfolk and Western Railway.

The Y6b was known as the workhorse of the Norfolk and Western Railway and the epitome of the compound mallet development design.

They were an improvement of the previous Y6a class with the only difference between the Y6as and the Y6bs was that the Y6bs were longer than the Y6as, had a larger firebox and had a greater tractive effort. more…

Shay N XL L M4

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 more…

Soo Line 1003 2-8-2 N XL L M4

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 more…

SP 4449 GS-4 4-8-4 N XL L M4

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, more…

SP Cab Forward 4-8-8-2 N XL L M4

Cab Forwards were designed to keep the crews from getting asfixiated from smoke while long tunnels. While a few other railroads considered purchasing the design, only the Southern Pacific Railroad ever bought any. Many wheel arrangements were used but most of them were of the 4-8-8-2 design.

AC-6 through AC-12 Cab Forwards Used a Saturated airpump mounted on the front of the boiler. These had a very distinct sound which we have gone through great lengths to duplicate.

UP 4-6-6-4 Challenger N XL L M4

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.

UP 4-8-4 FEF N XL L M4

Equipped with ESU "FULL THROTTLE STEAM" features!

Recorded from UP FEF 4-8-4 Northern #844
Built in 1944 Steam Locomotive No. 844 is the last steam locomotive built for Union Pacific Railroad. Made for passenger service it also hauled some freight in the late 1950s. Still serving today it has become Union Pacific's "Living Legend" as it holds the world record for longest contiuosly running steam locomotive!

With 80 inch Drivers, 300lbs of boiler pressure, and designed to safely operate at 120 more…

UP 4-8-8-4 Big Boy N XL L M4

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 more…
