If you already know the ESU project ID (5-digit code), simply enter it in the search field.

As a General Reference:
ANY LokSound V4.0 Sound file can be written to ANY LokSound V4.0 decoder. This means you can write a Micro(N Scale) 748xx file to an 8 pin or 21MTC V4.0, and alternately a 744xx(HO Scale) file to a Micro or V4.0 Direct decoder. The ESU LokProgrammer software will recognize the difference and ask you to proceed. By Accepting you are giving the permission needed for the LokProgrammer to automatically make the conversion needed.

  •   *SP Cab Forward*

    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.

    Many Cab Forwards also contained a Seperate Air Horn. This Sound Profile also contains the ability to play this horn sound using Function 12. (remappable if desired)

    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 Big Boy*

    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.

  •   Shay

    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.

    This ESU LokSound V4.0 File has 5 Whistles, which can be changed by setting CV48 to a value between 0 and 4.
