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 information presented following was cumulated from the January 1955 edition of the ORER (Official Railroad Equipment Register). The data pages for the Pennsylvania Railroad indicate that the data is current as of October 1, 1954.

Subclasses are tallied separately, with the exception of H21a, H21b, and H21e hopper cars which which were listed in different combinations, but combined here as "H21a & variants".

The list only takes into account equipment available for interchange, so does not include miscellaneous and maintenance of way equipment. 

The referenced HO scale models are listed based on how the cars are lettered... not what they best represent. Some cars show comments as to their appropriateness, while cars that have not been evaluated are followed by a "(?)". "(OOB)" indicates that the manufacturer is out of business.

My compilation shows a total fleet of 183,689 cars available for interchange, broken out by Box, Gondola, Stock, Coke, Hopper, and Flat car types.

General Information

Gregg Mahlkov writes "Fresh fruits and vegetables went to two types of consignees. The largest portion, by 1954, would have gone to grocery store chain warehouses, like Acme Markets of Philadelphia. The remainder would have gone to the "Pennsylvania Produce Terminals" in the larger cities, where it was sold by brokers who maintained offices and leased trackage in the terminal and sold to restaurants and independent grocery stores."

Union Tank Car Company was founded in 1866 by Captain Jacob J. Vandergrift, in response to the economic activities of John D. Rockefeller in the years leading up to his creation of Standard Oil. Vandergrift was involved in the conflicts in the oil regions of Western Pennsylvania in the 1860s–1870s. Eventually, Union Tank Car Company and Vandergrift's other holdings, which included pipeline and riverboat transport companies, merged with the company that later became Standard Oil. Rockefeller, once Captain Vandergrift's nemesis, made him Vice President of Standard Oil. The town of Vandergrift, Pennsylvania, built in 1895 by steel company president George G. McMurtry to house his workers, was named in Vandergrift's honor.
