The 567 prime mover is a line of medium-speed diesel engines manufactured by GM Electro-Motive Division. They were used in many EMD locomotives from 1938-1966 when it was replaced by the EMD 645. The 567 proved to be exceptionally successful in passenger, switching, freight, marine and stationary services. The 16 cylinder 567C variation could be found in the following locomotives:
FP7, FP9, FL9, FT, F2, F3, F7, F9, GP7, GP8, GP9, GP10, GP11, BL2, GP18, GP28, SD7, SD9, SD18
Recorded from a EMD GP9
This project is a normal idle version. It has 2 exhaust stacks.
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 notching. 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

95829.6 - SW1200 - Southern Pacific
The SW1200 was the third model of 1200 hp SW series switchers built by EMD. It was a successor to the SW7 and SW9. Compared to its direct predecessor, the SW9, the SW1200 differed in that it used the improved and more reliable 567C engine, compared to the SW9's 567B engine. Late SW1200s built in 1966 were instead built with the 567E 12-cylinder engine. Most of the locomotive's external features were unchanged from the SW9, making distinguishing between the two models difficult.
SW1200 production began in January 1954, immediately after SW9 production came to an end the previous month. Production continued for 12 years until the last SW1200 left EMD's manufacturing facility in May 1966.
Like many EMD products, customers could customize their SW1200 orders. Several types of trucks were available, including Flexicoil trucks and the standard Blomberg B trucks.[1] A few units were built with dynamic brakes, featuring a large square box with a fan on top of the hood, right in front of the cab.

The EMD SD30C-ECO is a 3,000-horsepower (2,200 kW) C-C diesel-electric locomotive built by EMD. Although similar to the EMD SD32ECO, the SD30C-ECO follows the Canadian Pacific Railway's request for crashworthiness and EPA emission standards with the "C" in the designation denoting crashworthiness of the cab, frame, and fuel tank. CP requested relaxed emission standards (Tier 0+ instead of Tier 2) to cut costs.
Cores for the locomotives come from CPs fleet of EMD SD40-2s. The frames, trucks, and internal components are reused while a new (standard) cab, designed and constructed by EMD, and a fuel tank is built new for each unit. With the increased emissions requirements, the locomotives feature flared radiators similar to those on the EMD SD45 to house additional cooling equipment. The locomotives have a snoot nose to house additional electronics, and all lighting with the exception of the headlights and ditch lights are LED.
This project has a notch based low idle with automatic high idle. It has a single turbo 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.

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.

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:
C425, C628
Other locomotives using variations of the 16cyl 251 prime mover included:
RS27, C424, C430, RSD-15, C630, C636, WDM-2 (Indian Railways)
Recorded from a ALCO C-425
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.

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
Export locomotives:
GT26MC, GT26CW, GT26CW-1, GT26CW-2, GT26CU-2
Recorded from a EMD SD40-2 "Snoot Nose"
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 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:
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

To turn the feature ON - Auto Bell ON:
1. ADD the Auto bell sound slot from the function mapping chart

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.
