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 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.

Between 1981 and 1983 Chessie rebuilt 67 EMD GP30 locomotives.
These were B&O and C&O GP30 units that went through Chessie's rebuilding program at both the Huntington and Cumberland shops. After rebuilding Chessie did not renumber the units, but CSX decided to give them their own number series once they took ownership.
GP-30Ms were internally rewired with some modular components similar to Dash 2 units. They also recieved new IDAC wheel slip control, D77 traction motors, and cab heaters. The orginal 567D prime mover retained turbocharging, but also recieved 645 Power Assemblies.
Recorded from a EMD GP30M
This project is a normal idle version. It has a single turbo early exhaust stack.
File also contains an "Isolation Switch" Mode on F15 when Standing Still.
Pressing F15 while not moving will lower the prime mover and lock the motor. F15 must be turned off to begin moving.
Another Mode is "Reverser In Center Position". When pressing F24 while stopped, the motor will lock so you can throttle through the notches like the prototype in neutral. F24 must be turned off to begin moving.
This project has "Run 8" mode. When turning on F26 with F28 off, the prime mover goes to run 8. Turning off F26 returns the prime mover sounds back to normal mode.
This project has "Coast" mode. When turning on F27 with F28 off, the prime mover goes to idle for coasting purposes. Turning off F27 returns the prime mover sounds back to normal mode.
You can still use F26 and F27 for manual nothing. You have to keep both F26 and F27 off before pressing F28 to turn on manual notching. Once F28 is on, you can use F26 to notch up and F27 to notch down. F26, F27, and F28 must be turned off to return to normal mode.
This project has "Load" mode. When turning on F29 with F15, F24, F26, F27, F28 off, the prime mover goes into load mode. While you are using load mode, the prime mover will notch up 1 or more notches based on primary load settings(CV104). The throttle notches up using speed instead of requested speed while using the load feature. F29 must be turned off to return to normal mode.

Auto Bell:
Many Second and Third Generation locomotives have been fitted with an Automatic Bell that is triggered when the horn is blown. In MANY cases this cannot even be bypassed on modern locos. Before the FRA mandated this feature on new locomotives the bell was of course turned on and off separately. Some locomotives were delivered with a manual bell and have been converted to an automatic bell. This creates a challenge in sound file creation.
We realize that not every loco with a particular prime mover had this feature. As such we have built in an option to turn the feature on and off. We will set the default in the file to be what is most appropriate for the particular file.
To turn the feature OFF - Auto Bell OFF:
1. Remove the Auto bell sound slot from the function mapping chart
CV31 = 16, CV32 = 8
----------------------
CV311 = 4
2. Change the sound configuration of the Auto bell sound slot
CV31 = 16, CV32 = 1

The ALCO 251 prime mover was the most popular and abundant prime mover ever made by the company. While it proved to be quite successful, it sadly outlived its original manufacturer. ALCO closed their doors in 1969. The 251 prime mover is actually still available to purchase today from Fairbanks Morse for use in marine, generator and locomotive uses.
Our recording is from a 16cyl 251C and could be found in the following locomotives:

The EMD 645 series was an evolution of the earlier 567 series and a precursor to the later 710 series. When the 645 prime mover entered production in 1965, a large series of new locomotive models was introduced. The turbocharged version was used in EMD's 40 Series (GP40, SD40 and SD45) in 3,000 horsepower (2,200 kW), sixteen-cylinder form and in 3,600 horsepower (2,700 kW), twenty-cylinder form. EMD also introduced the Roots-blown 38 Series (GP38, SD38) and turbocharged, twelve-cylinder 39 Series (GP39, SD39). All of these locomotive models extensively share common components and subsystems, thereby significantly reducing cost and increasing interchangeability. The GP38-2 and SD40-2 became the most popular models of the series and among the most popular locomotive models ever built.
This 16cyl 645E3 with Turbo sound file would be appropriate for the following locomotives:
GP40, GP40P, GP40P-2, GP40-2, GP40X, SD40X, SD40A, SD45T-2, SD40-2, SD40-2W, SD40-2S, F40C, F40PH, F40PH-2, F40PH-2M, SDP40F, SD40-2F

This project is a reverser based low idle version. It has a single turbo early exhaust stack.
File also contains a "low Idle" Mode on F15 when Standing Still.
Pressing F15 while not moving will lower the prime mover and lock the motor. F15 must be turned off to go to "regular idle" and begin moving.
Another "low Idle" Mode is reverser in center position. When pressing F24 while stopped, you can throttle through the notches like the prototype in neutral. F24 must be turned off to go to "regular idle" and begin moving.
This project has "Run 8" mode. When turning on F26 with F28 off, the prime mover goes to run 8. Turning off F26 returns the prime mover sounds back to normal mode.
This project has "Coast" mode. When turning on F27 with F28 off, the prime mover goes to idle for coasting purposes. Turning off F27 returns the prime mover sounds back to normal mode.
You can still use F26 and F27 for manual nothing. You have to keep both F26 and F27 off before pressing F28 to turn on manual notching. Once F28 is on, you can use F26 to notch up and F27 to notch down. F26, F27, and F28 must be turned off to return to normal mode.

This file is custom mapped for the Athearn SD70ACU Locomotives using a 58429 ESU LokSound 21MTC decoder and the factory Athearn Motherboards.
As there are 2 different startups on the SD70ACU, Air Start for NS and Electric Start for CP, we have created a file for each version:
12493.1 Canadian Pacific Electric Start Version with Nathan K3L Horn
12493.2 Norfolk Southern Air Start Version with Nathan K5LA Horn
In some cases the railroads varied on horns. Please use the list below to set the appropriate horn and bell for your roadname using CV163 and CV164.
The EMD SD70ACU is a 6-axle 4,300 hp (3,200 kW) diesel-electric locomotive originally built by General Motors Electro-Motive Division as an SD9043MAC, and rebuilt by Norfolk Southern and Progress Rail. They are operated by two railroads, Norfolk Southern railway and Canadian Pacific.
The SD70ACU began under Norfolk Southern, who rebuilt its EMD SD90MACs to this configuration at its shops in Altoona, Pennsylvania. The first locomotive entered the rebuilding process in September 2015, which was number 7299. As of 2019, all 110 units have been released into active service.
All of the SD70ACUs will be rebuilt with the latest EMD cab which meets current FRA crashworthiness standards. The Siemens electronics will be replaced with Mitsubishi electronics. The rebuild also includes the installation of Ultra Cab II, locomotive speed limiter (LSL), and cab signals. The trucks will be rebuilt only as needed and they are not getting traction motors swapped out.
In 2018, Canadian Pacific started a similar rebuild program with its long dormant SD90MAC fleet. Unlike NS, the work on these rebuilds was not be done in-house, but by Progress Rail at its Mayfield, Kentucky and Muncie, Indiana facilities.
In early 2021 CP bought 40 more SD90MACs from Union Pacific to continue the SD70ACU rebuild program. Some CP-patched, ex-Union Pacific SD90MACs have already been seen heading to Canada prior to rebuilding.
While not directly recorded from a SD70ACU we believe this to be an accurate representation using very similar recordings.
This project is a special notch based low idle with an automatic high idle version. It has a single turbo late (silenced) exhaust stack.
This ESU Sound file will operate like the prototype in terms of throttle notching. You will notice there is low and high idle, and once above notch 3 and back to Idle the prime mover will stay up in high idle for a period of time. Once in low idle throttling up to notch 1 or notch 2 and return to idle will stay in low idle.
File also contains an "Isolation Switch" Mode on F15 when Standing Still.
Pressing F15 while not moving will lower the prime mover to a "Low Idle" and lock the motor. F15 must be turned off to begin moving.
Another Mode is "Reverser In Center Position". When pressing F24 while stopped, the motor will lock so you can throttle through the notches like the prototype in neutral. F24 must be turned off to begin moving.
This project has "Run 8" mode. When turning on F26 with F28 off, the prime mover goes to run 8. Turning off F26 returns the prime mover sounds back to normal mode.
This project has "Coast" mode. When turning on F27 with F28 off, the prime mover goes to idle for coasting purposes. Turning off F27 returns the prime mover sounds back to normal mode.
You can still use F26 and F27 for manual nothing. You have to keep both F26 and F27 off before pressing F28 to turn on manual notching. Once F28 is on, you can use F26 to notch up and F27 to notch down. F26, F27, and F28 must be turned off to return to normal mode.
This project has "Load" mode. When turning on F29 with F15, F24, F26, F27, F28 off, the prime mover goes into load mode. While you are using load mode, the prime mover will notch up 1 or more notches based on primary load settings(CV104). The throttle notches up using speed instead of requested speed while using the load feature. F29 must be turned off to return to normal mode.
This file is also equipped with a Smart Start feature that cycles the prime mover on and off at intervals of your choice if the throttle is left at Idle and the loco is stopped.

Auto Bell:
Many Second and Third Generation locomotives have been fitted with an Automatic Bell that is triggered when the horn is blown. In MANY cases this cannot even be bypassed on modern locos. Before the FRA mandated this feature on new locomotives the bell was of course turned on and off separately. Some locomotives were delivered with a manual bell and have been converted to an automatic bell. This creates a challenge in sound file creation.
We realize that not every loco with a particular prime mover had this feature. As such we have built in an option to turn the feature on and off. We will set the default in the file to be what is most appropriate for the particular file.
To turn the feature OFF - Auto Bell OFF:

The GE Dash 8-32BWH, also known as the P32-8BWH, B32-8WH, or P32 DASH-8, is a passenger train locomotive used by Amtrak, based on GE's Dash 8 series of freight train locomotives. Built in 1991, they were the first locomotives purchased to replace the EMD F40PH.
The Dash 8-32BWH operates in a diesel-electric configuration that uses DC to power the traction motors, producing 3,200 hp (2,400 kW) at 1047 rpm. When providing head end power to the train, the engine is speed locked to 900 rpm. Power output to the traction motors is 2,700 hp (2,000 kW) when running in HEP mode with a 0 kW HEP load. Traction horsepower decreases to a bare minimum of 1,685 hp (1,257 kW) when providing the maximum 800 kW (1,100 hp) HEP load to the train.
The Dash 8-32BWH has a 74:29 gear ratio, resulting in a maximum operating speed of 103 mph (166 km/h) in passenger operation.
Recorded from a GE B32-8
This project is a normal idle version. It has a single late (silenced) exhaust stack.
File also contains an "Isolation Switch" Mode on F15 when Standing Still.
Pressing F15 while not moving will lower the prime mover and lock the motor. F15 must be turned off to begin moving.
Another Mode is "Reverser In Center Position". When pressing F24 while stopped, the motor will lock so you can throttle through the notches like the prototype in neutral. F24 must be turned off to begin moving.
You can still use F26 and F27 for manual nothing. You have to keep both F26 and F27 off before pressing F28 to turn on manual notching. Once F28 is on, you can use F26 to notch up and F27 to notch down. F26, F27, and F28 must be turned off to return to normal mode.
This project has "Load" mode. When turning on F29 with F15, F24, F26, F27, F28 off, the prime mover goes into load mode. While you are using load mode, the prime mover will notch up 1 or more notches based on primary load settings(CV104). The throttle notches up using speed instead of requested speed while using the load feature. F29 must be turned off to return to normal mode.
This file has a Special feature providing the sounds and operation of the Head End Power unit. This is used on the prototype loco to provide electricity to the coaches as these locos are almost always used in passenger service.
To engage HEP you must be stopped in Idle. Pressing F26 (Shift 2) will engage the HEP unit and allow the prime mover to run at a higher RPM.
When in stations often the engineer will go into Standby mode to preserve fuel and to allow the noise levels to come down a little. Pressing F27 on the throttle once HEP has already been engaged will allow the prime mover to come down a little. Again this can only be done while sitting still as on the prototype there is not enough RPM to provide power to the coaches and traction motors at the same time in Standy Mode.
This file is also equipped with a Smart Start feature that cycles the prime mover on and off at intervals of your choice if the throttle is left at Idle and the loco is stopped.

In the Mid 1980s GE changed it's 16cyl FDL design to include a different exhaust silencer, a new electric compressor often known as the "Whoop compressor" and changed some of the electronics of their locomotives. These differences among a few other led to a distinct change in the sounds from the GE 16cyl FDL often found from the U25Bs on through the Dash-7 series of the Locomotives.
Keeping in tradition with GE's locomotive series nicknames beginning with the "Dash 7" of the 1970s, the C44-9W was dubbed the Dash 9 upon its debut in 1993.
The "Dash-9" GE 16-7FDL16Y2 Prime mover can be found in the following Locos:
Dash 9-40C, Dash 9-40CW, Dash 9-44CW, C44-9WL, C44-9WM
It is also very close to the following locos:
AC44C6M, AC44C4M, Dash 8-39B, Dash 8 40-B, Dash 8-40BW, Dash 8-39C, Dash 8-40C, Dash 8-40CM, Dash 8-40CW, Dash 8-41CW, Dash 8-44CW, C38EMi, C38AChe, AC4400CW
Some AC6000CW were built with 7FDL-16cyls and were later converted to 7HDL-16cyl. Some were never converted. Please refer to the prototype for reference.

This file was made SPECIFCALLY for the Athearn SD80MAC and is function mapped for their lighting. This special mapping includes the "Pusher Lights" on F5
The SD80MAC is a 5000 horsepower C-C diesel-electric locomotive. The SD80MAC uses a 20 cylinder version of EMD's 710G prime mover,formally known as the V-20 710G3B-ES and is the first diesel locomotive to use a 20-cylinder engine since the SD45/SD45-2. The SD80MAC introduced a wide radiator housing similar to GE locomotives and the placement of dynamic brakes at the rear of the locomotive. Key spotting difference between the SD80MAC and SD90MAC include: no external rear sandbox on the 90MAC, rear number boards, and the placement of the front numberboards (above the cab windows on the SD80MAC, on the nose on most SD90MACs). The SD80MAC also has recessed red marker lights in the nose, an identifying feature unique to Conrail locomotives, although NS has removed the lights on most of their former Conrail engines.
We've tried to be as prototypical as possible with this iconic locomotive. Because of this, the notching on this SD80MAC file may be slightly different from what you are used to. Like many modern EMDs there is a warm-up cycle when you initially turn on the prime mover. This will cause the prime mover to rise and hold for a short period of time. There is also a high and low idle dictated by the isolation switch. If the isolation switch is not activated Notch 1 and Notch 2 are the same as this is high idle. Activating the islolation switch will drop the sounds to low idle.
Recorded from a EMD SD80MAC
This project is an isolation switch based low idle version. It has a single turbo late (silenced) exhaust stack.
File also contains a "low Idle" Mode on F15 when Standing Still.
Pressing F15 while not moving will lower the prime mover and lock the motor. F15 must be turned off to go to "regular idle" and begin moving.
Another Mode is "Reverser In Center Position". When pressing F24 while stopped, the motor will lock so you can throttle through the notches like the prototype in neutral. F24 must be turned off to begin moving.
This project has "Run 8" mode. When turning on F26 with F28 off, the prime mover goes to run 8. Turning off F26 returns the prime mover sounds back to normal mode.
This project has "Coast" mode. When turning on F27 with F28 off, the prime mover goes to idle for coasting purposes. Turning off F27 returns the prime mover sounds back to normal mode.
You can still use F26 and F27 for manual nothing. You have to keep both F26 and F27 off before pressing F28 to turn on manual notching. Once F28 is on, you can use F26 to notch up and F27 to notch down. F26, F27, and F28 must be turned off to return to normal mode.
This project has "Load" mode. When turning on F29 with F15, F24, F26, F27, F28 off, the prime mover goes into load mode. While you are using load mode, the prime mover will notch up 1 or more notches based on primary load settings(CV104). The throttle notches up using speed instead of requested speed while using the load feature. F29 must be turned off to return to normal mode.
This project has "DPU" mode. When turning on F5, the headlight and red marker lights activate on the end of the locomotive that is opposite from the direction of travel.
This file is also equipped with a Smart Start feature that cycles the prime mover on and off at intervals of your choice if the throttle is left at Idle and the loco is stopped.
