ALCO 12-244 Ed2

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…

EMD 16-645E 2EXH NT Ed3

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…

EMD 16-567B 2EXH NT

The EMD 567 is a line of large medium-speed diesel engines built by General Motors' Electro-Motive Division. The EMD 567 16cyl Prime Mover was one of the most widely used Prime Movers in the world and was used from 1938 until its replacement n 1966. From F-Units to Geeps this popular power house can still be found in many locomotives riding the rails today. Alle 567 engines are two-stroke V-engines with an angle of 45° between cylinder banks, a bore of 8,5 in (216mm) and a stroke of 10 in more…

EMD 12-1010J LATE EXH

EMD SD90MAC-H Phase II or SD70ACe-T4?

The SD70ACe-T4 is the Tier 4 emissions standards-compliant version of the SD70ACe. The first locomotive, EMDX 1501, was built in summer 2015, and made its debut at the Railway Interchange Expo in Minneapolis, Minnesota during the weekend of October 3–4, 2015. It features a new 4-stroke engine called the EMD 12-1010 "J" series - a V12 with 1010 cu.in displacement for each cylinder. This new prime mover has a two-stage turbocharger system consisting of more…

GMD 16-645E3-T

The EMD 645 series was an evolution of the earlier 567 series and a precursor to the later 710 series. When the 645 prime mover entered production in 1965, a large series of new locomotive models was introduced. The turbocharged version was used in EMD's 40 Series (GP40, SD40 and SD45) in 3,000 horsepower (2,200 kW), sixteen-cylinder form and in 3,600 horsepower (2,700 kW), twenty-cylinder form. EMD also introduced the Roots-blown 38 Series (GP38, SD38) and turbocharged, twelve-cylinder 39 more…

GE 16-7FDL16AE LATE EXH

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.

Keeping in tradition with GE's locomotive series nicknames beginning with the "Dash 7" of the 1970s, the C44-9W more…

ALCO 12-251B 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 1800 horsepower 12cyl version of the 251B could be found in the following locomotives:

RS-11, RSD-12, RS-18, RS-36, FPA-4, FPB-4, more…
