Southern Railway #630 was crafted by ALCO in 1904 under the Class K designation 2-8-0 consolidation. In 1917 it was significantly overhauled to include superheaters, piston valves, and Southern Valve Gear. It served the Southern Railway for the next 48 years primarily on the Asheville Division until retirement in June 1952.
#630 was then moved to Johnson City, TN where it found new life with the East Tennessee & Western North Carolina Railroad. It was numbered 207 and ran between Johnson City and Elizabethton. In 1967, the Southern Railway reacquired #630 in a trade to operate the locomotive as part of their steam program. It ran on the mainline once again until 1978.
The Tennessee Valley Railroad Museum (TVRM) then took #630 in under lease and it remained operational until 1989 and was retired. The locomotive was officially donated to the TVRM in 1999, restoration began in 2001 and completed in 2011. It continues to operate today at TVRM delighting passengers and railfans from all over the world.
We would like to send a Special Thanks to the TVRM for the opportunity to record the #630.

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.

Southern Railway #4501 was built in October of 1911 in Philadelphia by Baldwin Locomotive Works and assigned to haul freight trains on many different divisions of the Southern Railway system. It operated in Tennessee, Virginia, Kentucky, and Indiana. The locomotive was retired in July 1948 in favor of dieselization and was sold to the Kentucky & Tennesee Railway to haul coal trains. Once the K&T diselized in 1964, it was purchased by a railfan who brought it to Chattanooga, TN. It was returned to main line excursion service on the Southern's steam program started by W. Graham Claytor Jr. in 1966 through the cooperation of the railfan. It operated in this capacity until 1985 when it was replaced with larger locomotives. It then operated again between 1990 and 1994 in mainline excursion service, being removed due to Norfolk Southern discontinuing the steam program.
#4501 continued to operate for the Tennessee Valley Railroad Museum (TVRM) in Chattanooga until 1998 when its boiler ticket certificate expired.
Restoration work begain on #4501 in 2012 folloing the restoration success of the TVRM's #630. The restoration work was completed in 2014 and the locomotive currently operates in tourist excursion service at the TVRM for longer trips to Summerville, GA and for special TVRM excursion trains.
We would like to send a Special Thanks to the TVRM for the opportunity to record the #4501.

In 1899, the Florence and Cripple Creek Railroad (F&CC) acquired five T-19 Class locomotives for its Three-foot-network. Their heavy weight of 33 tons made these 2'C locomotives very powerful and they were used to pull passenger and freight trains. When the F&CC went bankrupt in 1916 due to severe flood damage, the locomotive, number 20, along with two sister locomotives, ended up with the Rio Grande Southern Railroad Company (RGS). In 1952, the RGS ceased operations and sold the locomotive to the Rocky Mountain Railroad Club, which later donated it to the Colorado Railroad Museum. It was restored to operating condition between late 2006 and mid-2020 with most of the work done by the Strasburg Rail Road in PA. It make it's official operational debut at the Colorado Railroad Museum on August 1, 2020.
#20 is in continual operation at the Colorado Railroad Museum for various events and has operated on other area narrow gauge railroads as a guest locomotive.
We would like to give Special Thanks to the Colorado Railroad Museum for their help in this project. To find out more about the museum and operations visit: https://coloradorailroadmuseum.org/

This is a 2-6-6-2T articulated Mallet that was built by The Baldwin Locomotive Works in 1926.
Pacific Northwest steam historian Martin Hansen offers this perspective: “This 1926 Baldwin 2-6-6-2T spent her entire working career in logging service in the Pacific Northwest. Originally ordered as a coal burner for the Potlach Lumber Co. of Potlach, Idaho where she was No. 24, she later converted to burn oil when she was purchased by Weyerhaeuser Timber Co. for use on that company’s Headquarters Operation out of Longview, Wash., where she became No. 108. She was one of only three Baldwin logging Mallets to be built with full saddle tanks over her boiler, rather than the more common split side tanks found on other tank Mallets of the day.”
The restoration on 108 was completed in 2020 and ran together with the ,110 another 2-6-6-2T, on the Blck Hills Central Railroads first double header.
True Mallet Locomotives are compound locomotives utilizing the steam multiple times. Because the exhaust from the first cylinders (high pressure) gets reused by the next set of cylinders (low pressure) the "double chuff" often associated with articulated locomotives is not really present. They are heard in the more common "simple" type articulated locomotives which are easier to mantain.
While recorded from a 2-6-6-2T this file can be used for simiar Compound Mallet type locomotives.

This is a 2-6-6-2T articulated Mallet that was built by The Baldwin Locomotive Works in 1928 for the Weyerhaeuser Timber Company of Vail, WA. Its next stop was The Rayonier Lumber Company where it received a tender from Rayonier #101 and was retired in 1968. This engine was later displayed at the Wasatch Mountain Railway in Heber City, UT, and then sold to the Nevada State Railway Museum. The #110 was sold to The BHC in 1999 and was trucked from Nevada to South Dakota on four semi-trailers. Restoration on this engine was completed in the spring of 2001.

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.

Equipped with ESU "FULL THROTTLE STEAM" features!
The name Challenger was given to steam locomotives with a 4-6-6-4 wheel arrangement. This means that they have four wheels in the leading "pilot" truck, which helps guide the locomotive into curves; two sets of six "driving" wheels, and finally, four "trailing" wheels, which support the rear of the engine and its massive firebox. Each set of driving wheels has its own steam cylinder. In essence, the result is two engines under one boiler.
The frame of the locomotive is "articulated," or hinged, to allow it to go through curves. When watching the approaching locomotive go through a curve, you can see the boiler swing out left or right independently of the lower half of the engine, as the rear half of the locomotive remains in a straight direction until its wheels and frame are halfway through the curve.
The Challengers were designed for fast freight service, but occasionally pulled passenger trains.
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.

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.

Recorded from Cumbres and Toltec #488
We would like to give a special thanks to the Cubres and Toltec Scenic Railroad for their help in this project. To find out more about their operation or to book a ride please go to: https://cumbrestoltec.com/
The Denver and Rio Grande Western K-36 class are ten 3 ft (914 mm) narrow gauge 2-8-2 "Mikado" type steam locomotives built for the Denver and Rio Grande Western Railroad (D&RGW) by Baldwin Locomotive Works. They were shipped to the Rio Grande in 1925 and were first used along the Monarch Branch and Marshall Pass, but were later sent to the Third Division out of Alamosa. Of the original ten, four are owned by the Durango and Silverton Narrow Gauge Railroad (D&SNG) and five by the Cumbres and Toltec Scenic Railroad (C&TS). Number 485 fell into the turntable pit at Salida and was scrapped in Pueblo in 1955, with many parts being saved.
The locomotives are of outside-frame design, with the driving wheels placed between the two chassis frames which support the boiler, but with the cylinders, driving rods, counterweights and valve gear on the outside. This general arrangement is shared with the earlier K-27, K-28 and later K-37 Mikado engines.
