ALCO 6-251C N XL L M4

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 who 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.

The 1000 horsepower 6cyl version of the 251C could be found in the following locomotives:

MLW S-13, MLW RS-23

EMD 16-645BC 4EXH NT N XL L M4

The Uceta GP16s were the result of a Seaboard Coast Line rebuild program upgrading GP7, GP9 and GP18 EMD locomotives. Unlike the GP10 program which retained a 567 16cyl prime mover, GP16s recieved 645 power assemblies. A 4 stack exhaust was also applied in most cases. Most ex GP7's had a 16-645BC prime mover. While ex GP9's in many cases had a 16-645C. In some rare cases some GP16's had a new 16-645E prime mover. US Army GP16's had brand new 645E's in them. Check your prototype. Today, many more…

CAT 3608 DII N XL L M4

CP 4711 was rebuilt in 1988 with a Caterpillar 3608 prime mover. In 1998 this loco was sold to Minnesota Commercial where is still resides today wearing Road number 71.
This sound file is appropriate for the following locomotives: M636

Please note this file has both air and electric starters. Please research your prototype to be sure of which starter to use. Recorded from a MLW M-636 Minnesota Commercial #71. This project is a normal idle version. It has a single exhaust stack.

ALCO 6-251B N XL L M4

The 48 Class are a class of diesel locomotives built by AE Goodwin, Auburn for the New South Wales Government Railways between 1959 and 1970. Once the most ubiquitous locomotive in New South Wales, Australia, they are based on Alco frames and prime movers, using General Electric (later Associated Electrical Industries) electrical equipment. The South Australian Railways 830 and Silverton Rail 48s classes are of a very similar design.

GE 16-7FDL16H9 LATE EXH N XL L M4

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 more…

EMD 16-567D2-T N XL L M4

The 567 prime mover is a line of medium-speed diesel engines manufactured by GM Electro-Motive Division. They were used in many EMD locomotives from 1938-1966 when it was replaced by the EMD 645. The 567 proved to be exceptionally successful in passenger, switching, freight, marine and stationary services. The 16 cylinder 567D2 Turbo variation was used in the following...

GTEL Turbine N XL L M4

Beginning in the 1950s, the Union Pacific Railroad sought higher and higher horsepower ratings from its locomotives to help move increasingly heavier and longer trains. Gas-Turbine Electric Locomotives (GTEL) technology promised much higher horsepower ratings over the diesel-electric locomotive designs of the time. General Electric (GE) and American Locomotive Co. (ALCO) built the first GTEL design, a double-ended, 4,500 horsepower, B+B – B+B unit, delivered as UP #50 in 1949.
