The Pennsy Modeler

In order to portray Pennsylvania Railroad and interchange partners as accurately as possible, this blog contains articles which are essentially notes to myself, but are shared should the community desire the same information.

Articles are sorted by modification date, so if an existing article receives an update it will be presented at the top of the list again.

GE U25B

GE U25B, Class GF25

The GE U25B was General Electric's first independent entry into the United States domestic road switcher diesel-electric locomotive railroad market for heavy production road locomotives since 1936. From 1940 through 1953, GE participated in a design, production, and marketing consortium (Alco-GE) for diesel-electric locomotives with the American Locomotive Company. In 1956 the GE Universal Series of diesel locomotives was founded for the export market. The U25B was the first attempt at the domestic market since its termination of the consortium agreement with Alco.

This table cross references Pennsy electric locomotives by class, type, sub class, sub class designator, year of introduction, and availability of HO scale models.

Eventually, clicking on minor class number will link to a class-specific page which will include prototype builder data, specifications, unit rosters, and unit photos.

Corrections and additions to this page are welcome. However, please refrain from submitting roster and subclass information for classes whose class detail pages have not yet been created. Thank you.

The following tables illustrate the various spotting features of EMD GP7 and GP9 units purchased by the Pennsylvania Railroad. The basis for these tables are from a Jim Williams presentation at the May 2000 annual meeting of the Pennsylvania Railroad Technical & Historical Society.

Alco RS-1, Class AS10s / AS10am / AS10ams / AS10as

The ALCO RS-1 was a 4-axle road switcher diesel-electric locomotive built by Alco-GE between 1941 and 1953 and the American Locomotive Company from 1953 to 1960. The Montreal Locomotive Works built three RS-1s in 1954. This model has the distinction of having the longest production run of any diesel locomotive for the North American market. The RS-1 was in production for 19 years from the first unit Rock Island #748 in March 1941 to the last unit National of Mexico #5663 in March 1960.

Broadway Limited Imports has been a champion in providing HO scale modelers with a breadth of fine steam locomotives. Herein is a listing of classes and road numbers released to date (may not be complete).

Road numbers in bold are in my personal collection (or on order).

Freight Locomotives


Baldwin DR 4-4-1500 "Early Shark", Class BF15 / BF15a

The Baldwin DR-4-4-15 was a 1,500-horsepower cab unit-type diesel locomotive built for freight service by the Baldwin Locomotive Works between November 1947 and June 1950. It was produced in two different body types, nicknamed the "Babyface" and "Sharknose" styles by railfans, though Baldwin used the same model number for both. 22 "Babyface" cab-equipped A units were built, along with 11 cabless booster B units; 36 "Sharknose" A units and 36 B units were constructed, making a total for all models of 105 locomotives built.

The Pennsylvania Railroad invested in diesel locomotives from all major manufacturers until EMD finally "won out" in the first generation diesel wars.

What follows is a timeline of diesel locomotive purchases by brand.

FM ERIE-A / B, Class FF20 / FP20 / FP20a

The Erie-built was the first streamlined, cab-equipped dual service diesel locomotive built by Fairbanks-Morse, introduced as direct competition to such models as the ALCO PA and EMD E-unit. As F-M lacked the space to manufacture the units in their own plant, the work was subcontracted out to General Electric, which produced the locomotives at its Erie, Pennsylvania, facility, thereby giving rise to the name "Erie-built."

This page chronicles the year that "modern" steam locomotive classes first appeared on the Pennsy, starting in 1900.

Going back before 1900, the results are really convoluted and inconsistent due to the PRR's absorption of subsidiary line's locomotives.
