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.

The Pennsylvania Railroad had operated a specially designed car constructed on a flat car. It's purpose was to accurately measure the distance above and/or adjacent to the tracks of bridges, tunnels, stations and rock cuts, etc.

The demaind for increased speed to shorten travel time in both present day industry and the business world has caused the railroad to provide more clearance for movement of equipment. The trend to larger equipment such as locomotives, passenger & freight cars and larger loads in open top cars has made the gathering of clearance information an area of growing importance. The Pennsylvania has spent millions of dollars to increase clerances for handling traffic. In the 1950s alone, the Panhandle Division tunnel project between Pittsburgh, Pa., and Dennision, Oh., cost over $8 million.

I've visited the following Pennsylvania Railroad model railroads and consider them to have a high degree of fidelity to the prototype. They are not freelance, protolance, etc., but depict specific locales on the Pennsy based on historic documentation.

When planning to model the Pennsy during the post World War II era, there are certain parameters which you may or may not wish to consider when selecting a year (or years) to depict. Among them may be paint schemes, specific models of diesel locomotives, specific models of freight cars, etc.

The graph below illustrates when certain features of the Pennsy came into play, or faded into history.



The Alco PA1 is considered one of the most attractive passenger locomotives ever built.

Early Trailer Numbering -- 1954-1959

The trailer number was broken into three parts. The first two digits indicated the trailer length. These two digits were followed by an alphabet letter (C, E, or W). The sig-nificance of the letter is unknown. The letter was followed by numbers indicating the trailer number. Thus trailer 32E250 is a 32’ trailer numbered 250.
