Recorded from Reading Northern #425
We would like to give a special thanks to the Reading and Northern Railroad for their help in this project.
Reading Blue Mountain & Northern Railroad 425 is a 4-6-2 light "Pacific" type steam locomotive originally built in 1928 by the Baldwin Locomotive Works for the Gulf, Mobile & Northern Railroad. After the GM&N was consolidated into the Gulf, Mobile & Ohio Railroad in 1940, the locomotive was renumbered #580 and served in passenger service before being retired in 1950. Today, the locomotive is owned and operated by the Reading & Northern Railroad, based out of Port Clinton, Pennsylvania in excursion service.
While recorded from a light pacific 4-6-2 this file can be used for smaller 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.

Virginia & Truckee #25 was built in 1905 by the Baldwin Locomotive Works of Philidelphia, Pennsylvania.
This was the second #25 owned by the V&T. The 4-6-0 steam locomotive, became the first new locomotive the V&T ordered since 1876.
The V&T #25 was originally a coal burner, but in 1907 it was converted into an oil burner, and became a also back-up locomotive. On occasions, the locomotive would haul both freight and passenger trains between Reno, Virginia City, and Carson, when the need for the engine to be used for back-up arised. From 1911 and 1937, the locomotive operated over 80,000 miles during it's service on the V&T. In 1938, V&T #25 was the locomotive that pulled the last scheduled passenger train to Virginia City.

The story of steam locomotive 8419 is as unique as the museum where it operates. In March of 1988, an article in National Geographic told about steam locomotives still being produced in China. A few months later, in May, two board members traveled to China to visit the factory and begin initial negations about purchasing a locomotive. When the locomotive rolled off of the line, the story is that the factory stopped production of steam locomotives, retooled, and began producing diesel electric locomotives. This makes 8419 the last commercially produced steam locomotive built in the world.
While built in China, this locomotive was purchased brand new and only used in the USA. It is very unique!
This Locomotive has a 2 Whistles and it's original Chinese Airhorn.
We have included multiple versions of each whistle in this file.

The Nevada Northern No. 40 is a 4-6-0 ten-wheeler type, steam locomotive which was built by the Baldwin Locomotive Works of Philadelphia, Pennsylvania in July 1910 for the Nevada Northern Railway Company.
It originally served as a passenger locomotive during the original years of when the Nevada Northern was a US Class 2 railroad as the main locomotive for the railroad's crack passenger train, the "Steptoe Valley Flyer". Before the Nevada Northern retired the locomotive in 1941, the locomotive was given a complete overhaul in secret by the shop crews in the Ely roundhouse. The locomotive was then put onto standby service. Afterwards, it was used in 1956 for the railroad's 50th Anniversary excursion and pulling a charter train for the Central Coast Railway Club in 1958 before being tucked back into retirement in the very back of the Ely roundhouse, preserved along with several passenger cars that were used with the locomotive since then. This was the last time the locomotive operated in revenue service. When the Nevada Northern shut down in the 1980's, the City of Ely was given the historic locomotive and train, along with the entire East Ely Yard, which was unaltered since being built in 1906, and any of the equipment and all of it which was inside the donated property. It is now currently used as a mixed traffic unit with the other Nevada Northern steam and diesel locomotives. But, its most famous role is the main locomotive for the "Ghost Train of Old Ely" excursion train.
Nevada Northern #40 ran it’s final excursion run on October 19th 2020, and it is now undergoing a complete rebuild.

The Heisler locomotive was the last variant of the three major types of geared steam locomotives.
Charles L. Heisler received a patent for the design in 1892, following the construction of a prototype in 1891. Somewhat similar to a Climax locomotive, Heisler's design featured two cylinders canted inwards at a 45-degree angle to form a 'V-twin' arrangement. Power then went to a longitudinal drive shaft in the center of the frame that drove the outboard axle on each powered truck through bevel gears in an enclosed gearcase riding on the axle between the truck frames. The inboard axle on each truck was then driven from the outboard one by external side (connecting) rods.
In 1897, Heisler received a patent on a three-truck locomotive. As with Class C Shay locomotives, the tender rode on the third truck. Unlike the Shay, Heisler's design did not have a continuous string of line shafting running the length of the engine. Instead, the tender truck was driven by a line shaft above the shaft driving the main engine trucks, connected to it through spur gears. This patent also covered use of a 4-cylinder 'vee four' cylinder configuration.
The Heisler was the fastest of the geared steam locomotive designs, and yet was still claimed by its manufacturer to have the same low-speed hauling ability.

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 2-10-0 represents the wheel arrangement of two leading wheels on one axle, ten powered and coupled driving wheels on five axles, and no trailing wheels. This arrangement was often named Decapod, especially in the United States.
These locomotives were popular in Europe, particularly in Germany and Russia; British use of the type was confined to the period during and after World War II. In the United States, the 2-10-0 was not widely popular but was a favorite of a small number of railroads which operated mostly in mountainous terrain. Among these was the Erie Railroad, a major Chicago to New York trunk line railroad.
The 2-10-0's main advantage was that five out of six of its axles were powered, meaning almost all the weight was available for traction rather than being distributed over pilot and trailing wheels. The long rigid wheelbase caused problems on tightly curved track, so blind drivers were the norm, either on the central axle, and/or on the second and/or fourth axles. Often lateral motion devices were attached to the leading drive axle.
The wheel arrangement's disadvantages included the firebox size restriction caused by the lack of trailing wheel. This meant the firebox was fitted in between the wheels (common on earlier locomotives) and was long and narrow, or if mounted above the driving wheels, was wide and long but shallow. Many locomotives chose the latter option. A firebox mounted over the drivers also restricted the diameter of the driving wheels, which in turn limited speed. As with the Consolidation (2-8-0), "chopping" at speed ensured a rough ride for the crew due to instability caused by the wheel arrangement. In fact, backing any locomotive without a trailing axle was restricted to under twenty miles per hour or less. Most 2-10-0s were not operated at speeds greater than 50 mph (80 km/h).
The type operated as freight engine, although locomotives in Germany and the United Kingdom proved capable of hauling passenger trains.

The 4-6-0 represents the configuration of four leading wheels on two axles in a leading bogie and six powered and coupled driving wheels on three axles with the absence of trailing wheels. In the mid 19th century, this wheel arrangement became the second most popular configuration for new steam locomotives in the United States of America, where this type is commonly referred to as a Ten-wheeler. As a locomotive pulling trains of lightweight all wood passenger cars in the 1890-1920s, it was exceptionally stable at near 100 mph speeds on the New York Central's New York to Chicago Water Level Route and on the Reading Railroad's Camden to Atlantic City, NJ, line. As passenger equipment grew heavier with all steel construction, heavier locomotives replaced the Ten Wheeler.
During the second half of the nineteenth and first half of the twentieth centuries, the 4-6-0 was constructed in large numbers for passenger and mixed traffic service. A natural extension of the 4-4-0 American wheel arrangement, the four-wheel leading bogie gave good stability at speed and allowed a longer boiler to be supported, while the lack of trailing wheels gave a high adhesive weight.
The primary limitation of the type was the small size of the firebox, which limited power output. In passenger service, it was eventually superseded by the 4-6-2 Pacific type whose trailing truck allowed it to carry a greatly enlarged firebox.
