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.

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.

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.
Disclaimer: This list may not take into account all rebuilds.

Alco FA1 / FB1, Class AF15
The ALCO FA was a family of B-B diesel locomotives designed to haul freight trains. The locomotives were built by a partnership of ALCO and General Electric in Schenectady, New York, between January 1946 and May 1959. They were of a cab unit design, and both cab-equipped lead (A unit) FA and cabless booster (B unit) FB models were built. A dual passenger-freight version, the FPA/FPB, was also offered. It was equipped with a steam generator for heating passenger cars.

Four Axle General Purpose (GP) Road Switchers
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.

When is an EMD "F7A" an "EF15a"? When it's owned by the Pennsylvania Rail Road!
The Pennsy - The Standard Railroad Of The World - had its own system of classifying diesel locomotives, rather than relying on the designations appointed by the builders of the units.
When the Pennsy first started purchasing diesel locomotives, they extended the classification system used for steam and electric locomotives, which was based on wheel arrangements. This sort of worked, until the arrival of the EMD E7's. The E7's were paired so "one unit" would have 4,000 hp. This produced a "powered" wheel arrangement of 0-6-6-6-6-0!

GATX Corporation (GATX) is an equipment finance company based in Chicago, Illinois. Founded in 1898, GATX's primary activities consist of railcar operating leasing in North America and Europe.
GATX derives its name from its primary reporting mark for its North American railcars, "GATX". The mark itself was derived from GATX's prior corporate name, "General American Transportation Corporation". History includes GATX working with famous designer Russel Wright to develop "Meladur", a famous melamine dinnerware from 1943-1945, using Melmac by American Cyanamid which was to be used on passenger cars and in hospitals marked with the name "General American".  Since all non-railroad owners of railcars must append an "X" to the end of their mark, GAT became GATX. GATX mainly applies the GATX mark to tank cars, although the mark has been used in other examples such as with hoppers; GATX's primary freightcar marks are GACX (for general-service freight cars), GGPX (for coal cars), GIMX (for intermodal cars), GPLX (for plastic pellet cars), GMTX and LLPX (for locomotives), and GPFX (for pressure-differential cars). GATX also owns a number of other marks, including GABX, GAEX, GFSX, GOHX, GSCX, IPSX, and TRIX. Many GATX cars carry a large "GATX" logo in the upper right-hand corner of the car regardless of the reporting mark they carry; this logo is applied for marketing reasons and does not have any operational significance.

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.

This table cross references Pennsy steam locomotives by class, type, sub class, sub class designator, year of introduction, and availability of HO 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.
Models in bold are in my personal collection.
