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.
The AEM-7 is a twin-cab four-axle 7,000 hp (5.2 MW) B-B electric locomotive built by Electro-Motive Division (EMD) and ASEA between 1978–1988. The locomotive was a derivative of the Swedish SJ Rc4 designed for passenger service in the United States. The primary customer was Amtrak, which bought 54 for use on the Northeast Corridor and Keystone Corridor. Two commuter operators, MARC and SEPTA, also purchased locomotives.

The Dual EMD 16cyl 645E3A prime movers were used in Union Pacific's DDA40X locomotive. Each of the two prime mover provides 3,300 hp. The DDA40X is the most powerful single-unit locomotive ever built.
As the DDA40X program was a test, a number of experiments were conducted during the service life of these locomotives. One such test included fitting a few of the units with air raid sirens to warn track-side personnel when away from grade crossings, but the results were inconclusive. Another more…
First made in the late 1930's the EMD 12cyl 567 Prime Movers were the power houses in many of EMD's Switchers. At the same time EMD found they could put 2 of these Prime movers together in one carbody to create a more powerful locomotive. Often geared for passenger service the E Units were created.

The Baldwin RF-16 was a 1,600-horsepower cab unit-type diesel locomotive built for freight service by the Baldwin Locomotive Works between 1950 and 1953. All RF-16s were configured with a B-B wheel arrangement and ran on two AAR Type B two-axle road trucks, with all axles powered. A total of 109 cab-equipped A units were built, along with 51 cabless booster B units, for a total of 160 locomotives built. As was the case with most passenger locomotives of its day, the RF-16s came equipped with a more…
The Iconic GG-1 is known around the world as the American Electric Streamliner. Built by GE and the famous Pennsylvania Railroad Altoona Shops the GG-1s were constructed between 1934 to 1943. Operating in a multitude of paint schemes the GG-1s ran on PRR, Penn Central, Conrail, Amtrak, and NJT. Primarily they ran on the North East Corridor between New York City and Washington DC. They did occasionally see service on other electric lines around the north east United States.
Though the GG-1 was 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.
"Galloping Goose" is the popular name given to a series of seven railcars (officially designated as "motors" by the railroad), built in the 1930s by the Rio Grande Southern Railroad (RGS) and operated until the end of service on the line in the early 1950s.
Originally running steam locomotives on narrow gauge railways, the perpetually struggling RGS developed the first of the "geese" as a way to stave off bankruptcy and keep its contract to run mail to towns in the Rocky Mountains in Colorado. more…
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 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.
Our recording is from a 16cyl - 251E and could be found in the following locomotives:
M630, M60W, C636, M636

EAs the EMD 567s got worn, Many Railroads underwent rebuild programs to prolong the life of their locomotives. One Program in particular was the Uceta GP-16 program on the SCL. Starting in 1979 they took many of their GP7s, GP9s, and GP18s and replaced the existing 567 prime movers with 16cyl 645C Power Assemblies. This combination resulted in a unique sound never before released in the Model Railroad Market.
There were a number of these rebuild programs by many railroads. CN Had GP9RMs, The more…
