Milwaukee Road 261 is a class "S3" 4-8-4 "Northern" type steam locomotive built by the American Locomotive Company (ALCO), in Schenectady, New York in July 1944, for the Chicago, Milwaukee, St. Paul and Pacific Railroad, often referred to as the "Milwaukee Road".
It was used for heavy mainline freight work until being retired by the railroad in 1956. Instead of being cut up for scrap, 261 was preserved and donated to the National Railroad Museum in Green Bay, Wisconsin in 1958. Today, the locomotive is owned, operated, and maintained by Minneapolis-based nonprofit organization Friends of the 261, which runs occasional and seasonal excursion trains using the locomotive. The steam engine, restored in 1993,[1] has logged more than 25,000 miles (40,000 km) under its own power since that time.
While recorded from an MILW S3 Class Northern this file can be used for many large locomotives in many wheel arrangments.

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 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.

The 0-6-0 configuration was the most widely used wheel arrangement for both tender and tank steam locomotives. The type was also widely used for diesel switchers (shunters). Because they lack leading and trailing wheels, locomotives of this type have all their weight pressing down on their driving wheels and consequently have a high tractive effort and factor of adhesion, making them comparatively strong engines for their size, weight and fuel consumption. On the other hand, the lack of unpowered leading wheels have the result that 0-6-0 locomotives are less stable at speed. They are therefore mostly used on trains where high speed is unnecessary.
Since 0-6-0 tender engines can pull fairly heavy trains, albeit slowly, the type was commonly used to pull short and medium distance freight trains such as pickup goods trains along both main and branch lines. The tank engine versions were widely used as switching (shunting) locomotives since the smaller 0-4-0 types were not large enough to be versatile in this job. 0-8-0 and larger switching locomotives, on the other hand, were too big to be economical or even usable on lightly built railways such as dockyards and goods yards, precisely the sorts of places where switching locomotives were most needed.
While recorded from an early 1920 0-6-0 this file can be used for smaller locomotives in many wheel arrangments.

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.

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.

Nickel Plate Road 765 is a class "S-2" 2-8-4 "Berkshire" type steam locomotive built for the New York, Chicago & St. Louis Railroad, commonly referred to as the "Nickel Plate Road". In 1963, No. 765, renumbered as 767, was donated to the city of Fort Wayne, Indiana, where it sat on display at the Lawton Park, while the real No. 767 was scrapped in Chicago in 1964.
In the early 1970s, the newly formed Fort Wayne Railroad Historical Society (FWRHS) restored No. 765 and operate it in main line excursion service. During the 1980s to early 90s, No. 765 ran excursion trains on the ex-Southern Railway's CNO&TP division and ex-Chesapeake and Ohio's New River Gorge route. Taken out of service in 1993, No. 765 was added to the National Register of Historic Places on September 12, 1996.
The No. 765 locomotive was completely overhauled and returned to service in 2005. Since 2010, it visited the Cuyahoga Valley Scenic Railroad, hauling several excursions every year. From 2012 to 2015, No. 765 ran excursions on Norfolk Southern trackage in Indiana, Missouri, New York, Ohio, Pennsylvania, and West Virginia, for the 21st Century Steam program. In 2016, it ran excursions on Metra's Milwaukee District North Line and even the Rock Island District Line in 2017 and 2018. Around 2022 and 2023, it visited the Indiana Northeastern Railroad for the Indiana Rail Experience excursions.

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 Shay locomotive was the most widely used geared steam locomotive. The locomotives were built to the patents of Ephraim Shay, who has been credited with the popularization of the concept of a geared steam locomotive.
Shay locomotives had regular fire-tube boilers offset to the left to provide space for, and counterbalance the weight of, a two or three cylinder "motor," mounted vertically on the right with longitudinal drive shafts extending fore and aft from the crankshaft at wheel axle height. These shafts had universal joints and square sliding prismatic joints to accommodate the swiveling trucks. Each axle was driven by a separate bevel gear, with no side rods.
The strength of these engines is that all wheels, including, in some engines, those under the tender, are driven so that all the weight develops tractive effort. A high ratio of piston strokes to wheel revolutions allowed them to run at partial slip, where a conventional rod engine would spin its drive wheels and burn rails, losing all traction.
Shay locomotives were often known as sidewinders or stemwinders for their side-mounted drive shafts. Most were built for use in the United States, but many were exported, to about thirty countries, either by Lima, or after they had reached the end of their usefulness in the US.

The GE 44-ton switcher is a 4-axle diesel-electric locomotive built by General Electric between 1940 and 1956. The locomotives were available with a choice of prime movers. Most were built with a pair of Caterpillar Inc.'s D17000 V8 180 horsepower (134 kW) engines. It was designed for industrial and light switching duties, often replacing steam locomotives that had previously been assigned these chores. This locomotive's specific 44-short ton weight was directly related to one of the efficiencies the new diesel locomotives offered compared to their steam counterparts: reduced labour intensity. In the 1940s, the steam to diesel transition was in its infancy in North America, and railroad unions were trying to protect the locomotive fireman jobs that were redundant with diesel units. One measure taken to this end was a stipulation that locomotives weighing 90,000 pounds (41,000 kg) or more required a fireman in addition to an engineer. The 44-ton locomotive was born to skirt this requirement. Other manufacturers also built 44-ton switchers of center-cab configuration. 348 examples of this locomotive were built for North American railroads. Many remain, in service and in museums.
Recorded from a GE 44-Tonner
This project is a normal idle version. It is an air throttle 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

2. Change the sound configuration of the Auto bell sound slot

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)
