The 4-12-2 represents the wheel arrangement of four leading wheels, twelve coupled driving wheels, and two trailing wheels. This arrangement was named the Union Pacific type, after the only railroad to use it, the Union Pacific Railroad.
Only one type of locomotive with a 4-12-2 wheel arrangement was built: the Union Pacific Railroad's 9000-series locomotives, 88 of which were built by ALCO between 1926 and 1930. These locomotives were used to increase the speed of freight trains in flat country, and were fairly successful, but were maintenance nightmares, largely because of their use of an inside third cylinder driving the cranked second driving axle between the frames. There was no inside valve gear to worry about, however. ALCO had obtained permission to use the conjugated valve gear invented by Sir Nigel Gresley. This system used two hinged levers connected to the outer cylinder's valves to operate the inner cylinder's valve. The 9000 class locomotives were the largest to use Gresley gear.
In this front view of the same locomotive the third cylinder and the mechanism that controlled it can be seen below the smokebox.
Between 1934 and 1940 eight of the first fifteen locos had their Gresley gear removed and were converted to a "double Walschaerts" valve gear which utilized a double eccentric (return) crank and second link on the right side (similar to the gear Baldwin used on its 3-cylinder experimental compound 4-10-2 #60000), which operated the valve for the inside cylinder. Union Pacific referred to this system as the "third link." The 4-12-2's constructed from 1928 utilized roller bearings in the Gresley lever bearings, thus none of these engines were converted. The pre-1928 engines not converted received the roller bearing levers in 1940, and no further conversions were made.
During design the third and fourth driving axles were planned to be "blind" (flangeless) in order to improve curve handling, but ALCO's lateral motion devices on the first and sixth axles (which allowed the axles to slide up to two inches to the side) made this unnecessary. They had the longest rigid wheelbase in North America, and the longest in the world until the Soviet Union built their 4-14-4 locomotive in 1934. The trailing truck carried the same axle load as the drivers, which was unusual.
There has been debate as to whether the first driving axle of the 4-12-2 was cranked to provide clearance for the main rod connected to the second axle. Union Pacific drawings show no such crank on the first axle, and the Railway Age article says "The 67 in (170 cm) drivers permit the use of a straight axle on the front drivers..." The spacing between the first and second axles was increased by 18 in (46 cm) to provide clearance. Based on the published dimensions, this means at its closest the centerline of the inside rod was 11.645 in (29.58 cm) from the centerline of the first axle. (UP drawings reproduced in Kratville and Bush's "Union Pacific Type" books show the inside rod 113 in (290 cm) long and the first and second driver axles 88 in (220 cm) apart. The inside cylinder axis was inclined 9.5 degrees and was 32 in (81 cm) above the plane of the driving axles at a point 181 in (460 cm) ahead of the second driving axle, so the cylinder axis missed the centerline of the second axle by 1-11/16 inches. The rod centerline is closest to the axle when the crank is 54.49 degrees below horizontal.)
There is one surviving UP 4-12-2 "Union Pacific" type locomotive. It is number 9000 displayed at the Los Angeles County Fairplex in Pomona, CA

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.

Southern Pacific 4449, also known as the Daylight, is the only surviving example of Southern Pacific Railroad's GS-4 class of steam locomotives and one of only two GS-class locomotives surviving, the other being GS-6 4460. The locomotive is a streamlined 4-8-4 "Northern"-type steam locomotive. GS is abbreviated from "Golden State", a nickname for California (where the locomotive was operated in regular service), or "General Service".
The locomotive was built by Lima Locomotive Works in Lima, Ohio, for SP in May 1941; it received the red-and-orange "Daylight" paint scheme for the passenger trains of the same name which it hauled for most of its service career. No. 4449 was retired from revenue service in 1956 and put into storage. In 1958, the SP donated the locomotive to the City of Portland, Oregon. The City then put the locomotive on static display in Oaks Amusement Park, where it remained until 1974.
The locomotive was then restored to operation for use in the American Freedom Train, which toured the 48 contiguous United States as part of the nation's 1976 Bicentennial celebration. The engine has operated in excursion service throughout that area since 1984.
The locomotive's operations are based at the Oregon Rail Heritage Center in Portland, Oregon, where it is maintained by a group of volunteers named the Friends of SP 4449. In 1983, a poll of Trains magazine readers selected 4449 as being the most popular locomotive in the nation.
This recording comes from SP 4449.

The EMD GP22ECO is a 2,150 hp (1,600 kW) B-B road switcher diesel-electric locomotive rebuilt by Electro-Motive Diesel and Norfolk Southern's Juniata Shops. Initially EMD built two GP22ECO demonstrators, one based on a GP9 and one based on a GP40,[1] but thus far all orders have been for conversions based on EMD GP40 and EMD GP40-2 series locomotives. The rebuild involves replacing the existing prime mover with an EPA Tier-II-compliant turbocharged V8 710G3A, with Electronic fuel injection. The prime mover is mated to an AR10 alternator for traction power, a CA6 alternator for control power, and a computerized control system. Applying this to a 6-axle locomotive results in a SD22ECO. Some 6-axle locomotives could alternately be converted into a SD32ECO, using a 3,150 hp (2,350 kW) V12 instead.
When applied to GP40 or GP40-2 series locomotives, this conversion does not alter the external appearance of the locomotive, although the conversion of the GP9-based demonstrator required extensive changes to the long hood. The GP22ECO offers customers a 'factory' upgrade of existing locomotives.
Norfolk Southern's units were rebuilt from GP38AC units. They also feature electrical, mechanical, and emissions improvements.
Recorded from a EMD GP22ECO
This project has a notch based low 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.
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

----------------------
CV311 = 12
2. Change the sound configuration of the Auto bell sound slot
CV31 = 16, CV32 = 1

The 2-8-2 wheel configuration on steam locomotives was one of the most highly used configurations made. This type of locomotive with 2 pilot wheels, 8 drive wheels, and 2 trailing wheels to support a larger firebox was first built for the Emperor of Japan, thus the name Mikado type. The first Mikado built for service in the US was built in 1901 and was owed by the Bismarck, Washburn and Great Falls until 1904 when it was acquired by the Soo Line.
This recording comes from the newer L-1 Class SOO Line 2-8-2 #1003. The SOO #1003 is a very average 2-8-2 not much different than the USRA light Mikado design. It does have slightly larger cylinders and a boiler pressure of about 170 PSI.
Originally delivered with a Westinghouse Cross Compound Air Pump, Walschaerts valve gear, an oil headlight, and a manual Johnson Bar, it was gradually upgraded to include a Power Reverse gear and electric headlights and class lights by about 1920.
It is important to note that wheel arrangement does very little to change the sounds of a steam locomotive. (Articulation aside). Boiler pressure, Stack size, Cylinder size and even the engineer at the throttle can all have more effect on the sound of locomotive than how many wheels are beneath it. While our dedication to accuracy is paramount, causing us to release very specific files, we will also be releasing some more generic files to try to give broad range to locomotives owned by MANY railroads. While this is a fairly common design and the sounds are similar to many locomotives, this ESU Full Throttle File is quite specific to the SOO #1003. We've included a few extra whistles for some variation.

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.

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 2-8-2 wheel configuration on steam locomotives was one of the most highly used configurations made. This type of locomotive with 2 pilot wheels, 8 drive wheels, and 2 trailing wheels to support a larger firebox was first built for the Emperor of Japan, thus the name Mikado type. The first Mikado built for service in the US was built in 1901 and was owed by the Bismarck, Washburn and Great Falls until 1904 when it was acquired by the Soo Line.
The USRA Heavy Mikado was a USRA standard class of steam locomotive designed under the control of the United States Railroad Administration (USRA), the nationalized railroad system in the United States during World War I. These locomotives were of 2-8-2 wheel arrangement in the Whyte notation, or 1′D1′ in UIC classification. A total of 233 locomotives were built to this plan for the USRA; postwar, it became a de facto standard design, which was built to the total of 957 locomotives including the USRA originals and all subsequent copies.
Heavy Mikado used the same running gear as the USRA Light Mikado but were built to a higher axle load, larger cylinders and a much larger boiler for more power and steam-generating ability. Many aspects of the PRR L1s class were carried over to the Heavy Mikado, although not that locomotive's distinctive Belpaire firebox

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.

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.
