ALCO Dual 6-539T

The ALCO 6cyl 539T engine was developed in response to the perceived drawback that ALCO's line of diesel switchers had a restricted field of vision because of the high hood. Both Baldwin and EMD were offering diesel switchers with a lower engine hood that the trainmen could see over.

The 539T was equipped with the Buchi turbocharger, being made under license by the Elliott Manufacturing Company of Jeannette, Pennsylvania.

Dual GE 16-FDL16 2EXH

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).

Essentially 2 U25Bs built on a single frame, the U50 was designed to replace the turbines on UP. Using scrapped Turbine frames 2 FDL 16 Prime movers were put together creating a 5000 more…

GE 16-FDL16

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…

ALCO 12-251C C420 ED2

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 12cyl 251C can be found in the following Locomotives:

RS-32, C420, M420, M420B, M420R, M420TR, HR-412, M424, 45 Class, 442 Class, 600 more…

FM 38D-6

The FM H-12-44 was a yard switcher produced by Fairbanks-Morse from May, 1950–March, 1961. The units featured a 1,200-horsepower (890 kW), six-cylinder opposed piston engine prime mover, and were configured in a B-B wheel arrangement mounted atop a pair of two-axle AAR Type-A switcher trucks, with all axles powered and geared for a top speed of 60 miles per hour (97 km/h).

A total of 303 units were built for American railroads, 30 were manufactured (between August 1951 to June 1956) by the more…

EMD 16-567D3 T

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 567D3 variation was used in the following...

Goodwin Alco 6-251B

48/830 Class Goodwin Alco 6cyl 251B
Recorded by Jay Blanch of Notch 8 Precision Models

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 more…

Goodwin/Alco 12-244

Recorded from 4306 at the Rail Transport Museum at Thirlmere.

In October 1956 the NSWGR took delivery of 4301, the first unit of an order for six locomotives to be built by A Goninan and Co at their Broadmeadow plant in suburban Newcastle. In June 1957 the last of the class, 4306, entered service. They were fitted with an Alco 244 engine and were rated at 1600hp (1193kW) for traction.

While recorded from a 43 Class this 12cyl 244 prime mover sound file would also work in the following more…

EMD 12-645E3 ED2

ED2-Second edition of this Popular Prime mover!

An SD39 is a 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division between August 1968 and May 1970. 54 were built for American railroads.

In 1966 EMD replaced all their old models with new ones having the new 645 diesel. These included six-axle models SD38, SD40, SDP40 and SD45; the SD39 was added in 1968. All shared standard components including the frame, cab, traction alternator, trucks, traction motors, and air more…

GE 16-7FDL Modern

Recorded from a B39-8E with modern "Whoop" compressor. Similar to a B40-8

In the Mid 1980s GE changed it's 16cyl FDL design to include a different exhaust silencer, a new electric compressor often known as the "Whoop compressor" and changed some of the electronics of their locomotives. These differences among a few other led to a distinct change in the sounds from the GE 16cyl FDL often found from the U25Bs on through the Dash-7 series of the Locomotives.

GE's AC series of locomotives were more…
