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.

Models in bold are represented in the author's collection.

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.

Lima-Hamilton LT-2500, Class LS25 / LS25m

The Lima-Hamilton 2500 horsepower Transfer locomotive (sometimes referred to by its Specification Number, A-3177 or the railfan designation LT-2500) was a diesel-electric transfer-unit locomotive, built by the Lima Locomotive Works between 1950 and 1951. The LT-2500 was the final locomotive model produced by Lima-Hamilton before the company merged with the Baldwin Locomotive Works in 1951.

All twenty-two units were purchased by the Pennsylvania Railroad.

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.

f30d w trailer

The F30 were 50' flat cars and the predominant flat car class on the Pennsy roster during the 1950s.

1956

The economic success of the railroads depended on freight shipped in full cars. The idea of putting truck trailers on flatcars was a method of moving less-than-carload shipments economically. This "intermodal" concept held the hope of competing with trucks which were taking more and more of this business from the railroads.

In the mid-thirties, the Chicago, the Great Western and then the New Haven railroads began piggy back service limited to their own railroad. By 1953, the CB&Q, the Eastern Illinois and the Southern Pacific railroads had joined the innovation. Most cars were surplus 50's flatcars equipped with new decks by the railroads. By 1955, an additional 25 railroads had begun some form of piggy back service. A significant legal battle between the truckers and the railroads resulted in a ruling permitting interstate piggy back service using either railroad or privately owned trailers. The stage was set for rapid expansion of intermodal services.

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!
