H0 N XL L M4 
CP 4711 was rebuilt in 1988 with a Caterpillar 3608 prime mover. In 1998 this loco was sold to Minnesota Commercial where is still resides today wearing Road number 71.
This sound file is appropriate for the following locomotives: M636
Please note this file has both air and electric starters. Please research your prototype to be sure of which starter to use. Recorded from a MLW M-636 Minnesota Commercial #71. This project is a normal idle version. It has a single 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

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

The 48 Class are a class of diesel locomotives built by AE Goodwin, Auburn for the New South Wales Government Railways between 1959 and 1970. Once the most ubiquitous locomotive in New South Wales, Australia, they are based on Alco frames and prime movers, using General Electric (later Associated Electrical Industries) electrical equipment. The South Australian Railways 830 and Silverton Rail 48s classes are of a very similar design.
The roughly 1000 horsepower 6cyl version of the 251B could be found in the following locomotives:
NSW 48 Class, SA 830 Class
And in some North American locos:
S-6, T-6
Other 6cyl 251 Variants sound almost identical and can be found in the following prototypes.
S-5, DL535E, DL535EW, MLW S-13, MLW RS-23
Recorded from a ALCO 48 Class

As the EMD 567s got worn, Many Railroads underwent rebuild programs to prolong the life of their locomotives. One Program in particular was the Uceta GP-16 program on the SCL. Starting in 1979 they took many of their GP7s, GP9s, and GP18s and replaced the existing 567 prime movers with 16cyl 645C Power Assemblies. This combination resulted in a unique sound never before released in the Model Railroad Market.
There were a number of these rebuild programs by many railroads. CN Had GP9RMs, The DM&IR had SD-Ms rebuilt from SD9's and SD18's and others. While there were different Exhuast configurations, This file will be very close to the following locomotives:
GP16, FP9U, GP9RM, SD9M, SD-M, GP7U (Some- Check your prototype)
The following locos were rebuilt from 567D Turbo locos, that have been de-turboed and repowered with the 645C Power Assemblies:
GP20E, GP20M, GP35M, GP35R, GP38M, SD18M, SD20-2, SD35R, SD20
Recorded from a EMD SD-M

The GE FDL-16 prime mover was first used in 1959 in the General Electric U25B locomotive. Over the years little changed in terms of sound until the "Dash-8" series of GE locomotives was introduced. Known for their throaty chug and shaft driven compressor (rather than the more modern “Whoop” electric compressor). There was an interim period following the "U Boats" that began the era in GE called the "Dash-7s". During this time many locos started receiving exhaust silencers and the shape of the exhaust changed to the "Bathtub" type. This created a subtle change in sound. The following GE locomotives used the 16cyl FDL prime mover with this type of configuration.
Locomotives:
B30-7, B36-7, C30-7, C36-7, and others.
The following locomotives would use early 16cyl FDL configurations, but this file would work for them as it is very close. Check your prototype as some of the later “U boats” were upgraded with more modern exhausts. You could also use our 73445/74445 GE 16cyl FDL Early file:
U25B, U28B, U30B, U33B, U36B, U25C, U28C, U28CG, U30C, U30CG, P30CH, U34CH, U33C, U36C

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 who 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.
The 12cyl 251C can be found in the following Locomotives:
RS-32, C420, M420, M420B, M420R, M420TR, HR-412, M424, 45 Class, 442 Class, 600 Class, 700 Class, A-321
The 2000 Horsepower 12cyl 251C version was extremely close to 251B in the way that is sounded. The 1800 horsepower 12cyl version of the 251B could be found in the following locomotives:
RS-11, RSD-12, RS-18, RS-36, FPA-4, FPB-4, RSC-14, FD-6, FD-7, FD-9, RSD-16, DL-560, 44 Class, 930 Class

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
----------------------
CV287 = 0
To turn the feature ON - Auto Bell ON:
1. ADD the Auto bell sound slot from the function mapping chart
CV31 = 16, CV32 = 8
----------------------
CV311 = 12
2. Change the sound configuration of the Auto bell sound slot
CV31 = 16, CV32 = 1
----------------------

The GE FDL-16 prime mover was first used in 1959 in the General Electric U25B locomotive. Over the years little changed in terms of sound until the "Dash-8" series of GE locomotives was introduced. Known for their throaty chug and shaft driven compressor (rather than the more modern “Whoop” electric compressor). There was an interim period following the "U Boats" that began the era in GE called the "Dash-7s". During this time many locos started receiving exhaust silencers and the shape of the exhaust changed to the "Bathtub" type. This created a subtle change in sound. The following GE locomotives used the 16cyl FDL prime mover with this type of configuration.
Locomotives:
B30-7, B36-7, C30-7, C36-7, and others.
The following locomotives would use early 16cyl FDL configurations, but this file would work for them as it is very close. Check your prototype as some of the later “U boats” were upgraded with more modern exhausts. You could also use our 73445/74445 GE 16cyl FDL Early file:
U25B, U28B, U30B, U33B, U36B, U25C, U28C, U28CG, U30C, U30CG, P30CH, U34CH, U33C, U36C
Recorded from a GE B36-7
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.
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.

GE Evolution 12cyl "GEVO" Locomotives have a 4 stoke diesel engine and have been designed to be more efficient and more emission friendly than previous models. Evolution Series locomotives are equipped with either AC or DC traction motors, depending on the customer's preference, though admittedly there is little sound difference if any between the two.
All early GEVOs were delivered with the Nathan Airchime K5HL air horn. Later GEVOs started to recieve a slightly different K5HLL horn. Most if not all have been delivered with a Graham-White 373 E-Bell. This E-Bell is tied to the horn circuit in the locomotive and will play automatically when the horn is played. The ESU version also has this new feature. The bell can be activated by either pressing F1 or by pressing the horn using F2. The "Auto-Bell" can be turned off by removing the the Auto-Bell sound slot from F2.
Another feature of the prototype is "Smart Start". For the sake of both emissions and fuel savings all GEVOs have been built with an auto shutdown/auto start feature. After the loco has been idle for a period time, the engine will shut down on its own. If the prime mover cools to a certain temperature the loco will automatically start again to keep from freezing.

New Orleans' St. Charles Streetcar Line is the world's oldest continuously operated electric railway line. Electric operation began in 1893, when streetcars took over after 20 years of horsecar operation. In 1922, operation of all New Orleans streetcar lines was taken over by New Orleans Public Service Inc., or NOPSI for short. In 1923, the current streetcars, designed and built by the Perley Thomas Car Company of High Point, North Carolina, were introduced. In 1973, the St. Charles Line and the remaining fleet of 35 Perley Thomas cars received national recognition when they were named to the National Register of Historic Places.
Many of these cars are still in use today!

Beginning in the 1950s, the Union Pacific Railroad sought higher and higher horsepower ratings from its locomotives to help move increasingly heavier and longer trains. Gas-Turbine Electric Locomotives (GTEL) technology promised much higher horsepower ratings over the diesel-electric locomotive designs of the time. General Electric (GE) and American Locomotive Co. (ALCO) built the first GTEL design, a double-ended, 4,500 horsepower, B+B – B+B unit, delivered as UP #50 in 1949.
This groundbreaking design would kick off the “Turbine Era” on the UP, which saw GE building successively larger and more powerful GTELs that would power UP’s hottest trains over the next two decades. The basic principal of the GTEL saw a GE-designed and built gas turbine… essentially a type of jet engine… driving a generator that produced electricity , which was fed to the traction motors on the locomotive’s axels. This design offered several advantages over more conventional diesel-electric locomotive designs of the era, particularly in horsepower. While competing cab and hood designs of the era boasted 1,500 – 1,750 hp, the first GTELs boasted 4,500 hp. Another advantage of the GTEL was it being designed to burn Bunker C heavy fuel oil, which, at the time, was much less expensive compared to conventional diesel fuel oil. GE would build successive batches of GTELs for UP, with each new design featuring improvements and design changes learned from experience from their predecessors.
Despite their outstanding performance, the “Big Blows” were to have relatively short careers. One of the contributing factors to this was rising fuel costs; the once-cheap Bunker C fuel oil the turbines were designed to burn, which refiners practically couldn’t give away early on, saw its price per gallon rise dramatically in the 1960s, eventually negating the fuel cost advantage the turbines enjoyed over their diesel-electric contemporaries. Rising maintenance costs compared to diesel-electrics also became an issue. The turbine engines were complex pieces of machinery compared to a typical diesel prime mover, in particular the delicate turbine fan blades. These factors, along with advances in diesel-electric locomotive horsepower, and limitations on where the GTELs could operate, saw the first of the “Big Blows”, UP 1-4, retired in August of 1968, after scarcely 10 years of service. Their numbers continued to dwindle over the last few years of the decade, with UP #7 holding the distinction of being the last “Big Blow” to operate, pulling its last train on December 26th, 1969. All were officially retired by February 1970, closing out the loud and exciting Turbine Era on the Union Pacific.
As the Evolution of the GTEL Turbines progressed multiple versions were created. Among these were Single Unit and A-B sets with the Hostler Motor in the A unit and the Turbine in the B Unit. The file contains both Hoslter Motor and Turbine in one decoder. If modelling a Single unit just plug in and go! If using this in an A-B set 2 decoders will be needed. Simply turn the volume of the Turbine down in the A Unit decoder, and turn the volume of the Hostler Motor to 0 in the B Unit. DO NOT DISABLE them from function mapping as the Hostler motor sounds "talk" to the Turbine sounds inside the sound schedules within the decoder.
This file does contain "Full Throttle" capabilities. While the Turbine does not go up and down once turned on the Full Throttle abilities allow the Turbine to be Consisted with Diesels as this became a common practice in the late 1950's
