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. With the Y6as only generating a tractive effort of 166,000 lbf (738.5 kN) and the Y6bs generating a tractive effort of 170,000 lbf (756.2 kN). The locomotives delivered 5,500 horsepower. The weight of a Y6b locomotive about 582,900 lbs with 522,850 lbs directly on the drivers.
When the Norfolk and Western Railway ceased their mainline steam operations in 1959, 50 of the Y6s were still running out serviceable miles in the coal fields waiting for the final order of diesels to replace them. The last of the Class Ys were retired in the summer of 1960.

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 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! For additional options there are 3 Braking rates that can be set up for user preference.
Articulation: Sound Slot 2
By adding Sound Slot 2 to the F8 Function Mapping and enabling the "Secondary Trigger" (CV250) 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.

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 GMD SD40-2
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 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.
Prime mover volume selection mode. By default the prime mover has volume dynamics. Meaning idle is soft while notch 8 is loud. This is very prototypical. The next option is volume maxed out. Meaning idle and notch 8 are the same volume. This is more suitable for people who like it loud.

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
----------------------

2. Change the sound configuration of the Auto bell sound slot
CV31 = 16, CV32 = 1

The Canadian National Railway (CN) rebuilt locomotives into GP9RM, with the "RM" denoting for "Remanufactured", the first batch of 37 GP9s were rebuilt between 1981 and 1984, and were numbered as 4000 through 4036, the second batch of 44 GP9s were rebuilt in two periods, with the first 17 being rebuilt in 1984, and the remaining 27 being rebuilt between 1989 and 1991, all of which were numbered 4100 through 4143, the third batch of 84 GP9s being rebuilt in two periods, with the first 14 being rebuilt in 1985, and the remaining 70 GP9s being rebuilt between 1991 and 1993, all of which were numbered 7000 through 7083, and there was the fourth batch of 81 GP9s divided into three periods, with the first 49 being rebuilt between 1985 and 1988, the second 22 being rebuilt in 1990, and the remaining 10 being rebuilt between 1993 and 1994, all of which were numbered 7200 through 7280.
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:
GP9RM, GP9U, 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 GMD GP9RM
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.
Prime mover volume selection mode. By default the prime mover has volume dynamics. Meaning idle is soft while notch 8 is loud. This is very prototypical. The next option is volume maxed out. Meaning idle and notch 8 are the same volume. This is more suitable for people who like it loud.

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.

General Electric produced the 70-ton switcher as a complement to its 44-ton model. The idea behind the development of the 70-tonner was to provide a locomotive suitable for branch lines, switching and transfer service. To be a success, the locomotive had to satisfy certain criteria. It had to be:
• Light enough to run on 50-pound rail and light bridges,
• Powerful enough to move long cuts of cars in switching or road hauls.
and
• Fast enough to make light passenger runs.
The 44-tonner could do most of these jobs adequately, but required multiple units to pull much weight. It was evident that a new locomotive was needed - one that would be larger than the 44-tonner, but smaller than the 1,000 - horsepower types such as Alco's S-2 or the EMD NW2, The 139,000 - pound weight (70 tons) was ultimately decided on, as it would run on light trackage without necessitating major rebuilding, but could pull twice as much tonnage as the 44-ton model.
A standard end-cab layout was dictated by a decision to use the Cooper-Bessemer FWL-6T, a six-cylinder, 600-horsepower engine, instead of two smaller engines, as in the 44-tonner. This body design also provided crew protection while operating in train service, and excellent visibility for switching. Power was transmitted to the wheels using a GE GT-571 generator and four GE 748 traction motors. This combination allowed for the development of 32,600 pounds of tractive effort and a top speed of 55 MPH. In early May 1946, demonstrator 7001 was outshopped and started touring the country, displaying the unit's virtues. Short lines especially were impressed with what they saw, and ordered many units. Stories of how the 70 tonner saved a dying short line were promoted in the railway press, and General Electric took advantage of this free publicity as an opportunity to build sales.
Among the many reasons listed for the short line resurrections were:
• Little or no rebuilding of the trackage was necessary to accommodate the units,
• Up to 95 percent availability of the unit, and
• A large reduction in fuel and maintenance costs over those of steam locomotives.
As production went on, the basic layout of the unit remained unchanged, but it was upgraded cosmetically as well as mechanically. By the end of production, tractive effort had been increased to 34,100 pounds (from 32,600 pounds), top speed was 60 MPH, and the engine developed 660 horsepower compared to the initial 600 horsepower.

The Pioneer Zephyr is a diesel-powered trainset built by the Budd Company in 1934 for the Chicago, Burlington & Quincy Railroad (CB&Q), commonly known as the Burlington Route. The trainset was the second internal-combustion–powered streamliner built for mainline service in the United States (after the Union Pacific Railroad's M-10000), the first such train powered by a diesel engine, and the first to enter revenue service.
The trainset consists of one power/storage car, one baggage/RPO/buffet/coach car, and one coach/observation car. The cars are made of stainless steel, permanently articulated together with Jacobs bogies. The construction incorporated recent advances such as shotwelding (a specialized type of spot welding) to join the stainless steel, and unibody construction and articulation to reduce weight. It was the first of nine similarly built trainsets made for Burlington and its technologies were pivotal in the subsequent dieselization of passenger rail service.
Its operating economy, speed, and public appeal demonstrated the potential for diesel-electric-powered trains to revitalize and restore profitability to passenger rail service that had suffered a catastrophic loss of business with the Great Depression. Originally named the Burlington Zephyr during its demonstration period, it became the Pioneer Zephyr as Burlington expanded its fleet of Zephyr trainsets.
On May 26, 1934, it set a speed record for travel between Denver and Chicago when it made a 1,015.4-mile (1,633 km) non-stop "Dawn-to-Dusk" dash in 13 hours 5 minutes at an average speed of almost 78 mph (124 km/h). For one section of the run, it reached a speed of 112.5 mph (181 km/h). The historic dash inspired a film ("The Silver Streak") and the train's nickname, "The Silver Streak".
The train entered regular revenue service on November 11, between Kansas City, Missouri; Omaha, Nebraska; and Lincoln, Nebraska. It operated this and other routes until its retirement in 1960, when it was donated to Chicago's Museum of Science & Industry, where it remains on public display. The train is generally regarded as the first successful streamliner on American railroads.
Though no Pioneer Zephyr runs today, we used an 8-567C prime mover for this project.
This project is a normal idle version. It is an air throttle version. It has switcher type exhaust with a single exhaust stack.

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 251B and could be found in the following locomotives:
RS27, C424, C430, RSD-15, C630, C636, WDM-2 (Indian Railways)
Recorded from a ALCO C-424
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 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.
Prime mover volume selection mode. By default the prime mover has volume dynamics. Meaning idle is soft while notch 8 is loud. This is very prototypical. The next option is volume maxed out. Meaning idle and notch 8 are the same volume. This is more suitable for people who like it loud.

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 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 C30-7
This project is a normal idle version. It has a single late (silenced) exhaust stack.
