EMD 8-645E NT N XL L M4

The EMD 645 family of diesel engines were designed and manufactured by the Electro-Motive Division of General Motors. The 645 series was an evolution of the earlier 567 series and a precursor to the later 710 series. The 645 series engines entered production in 1965. All 645 engines utilize forced induction, with either a Roots blower or a turbocharger. The 645 series has a maximum engine speed of between 900 and 950 revolutions per minute (rpm), an increase over the 800 to 900 rpm maximum more…

ALCO 12-244 N XL L M4

The American Locomotive Company's model 244 prime mover was developed during the mid-1940s to power its post-war diesel locomotives. Interestingly, while Alco helped pioneer diesel technology dating back to the 1920s it had difficulty truly competing against Electro-Motive-Division due to reliability issues with its diesel engines. Before Alco began implementing the 244 in its locomotives the builder had spent most of the 1930s developing an earlier model that was used in most of its early more…

ALCO 12-251C3 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 2000 horsepower 12cyl version of the 251C could be found in the following locomotives:

M420W, M420B, M420R, M420TR, HR-412, M424, RS-32, more…

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.

GE 16-7FDL12H18 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) , the following GE locomotives used the early 16cyl FDL prime mover:

U25B, U28B, U30B, U33B, U36B, U25C, U28C, U28CG, U30C, U30CG, P30CH, U34CH, U33C, U36C, B30-7, B36-7, C30-7, C36-7 more…


The GE B23-7 diesel locomotive was first offered in late 1977. Featuring a smaller 12 cylinder version of the FDL engine, it is the successor to GE's U23B produced from early 1968 to mid 1977, but at 62 ' 2" long, the B23-7 is exactly 2' 0" longer than the firms U23B. The B23-7 competed with the very successful EMD GP38-2. General Electric also produced a variant, the BQ23-7, for the Seaboard Coast Line. A total of 537 B23-7's were built for 9 U.S. customers and 2 Mexican customers.

BLW 8-608SC N XL L M4

The Baldwin AS-616 was a diesel-electric locomotive of the road switcher type rated at 1,600 horsepower (1,200 kW), that rode on three-axle trucks, having a C-C wheel arrangement.
Nineteen railroads bought 214 locomotives, and two railroads bought seven cabless B units.
Used in much the same manner as its four-axle counterpart, the Baldwin AS-16, though the six-motor design allowed better tractive effort at lower speeds.

GE Evolution 12cyl "GEVO" Locomotives have a 4 stoke diesel engine and have been designed to be more efficient and more emission friendly than previous models. Evolution Series locomotives are equipped with either AC or DC traction motors, depending on the customer's preference, though admittedly there is little sound difference if any between the two.

All early GEVOs were delivered with the Nathan Airchime K5HL air horn. Later GEVOs started to recieve a slightly different K5HLL horn. Most if more…

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.

The roughly 1000 horsepower 6cyl version of the 251B could more…
