| M.U. Electrics. Here is an original photo that I took of Pennsylvania Railroad equipment in Hollidaysburg, Pennsylvania, on 03 July 1965. Shown here is a close-up of PRR #4533, an MBM-62T (Mail Car) built by American Car & Foundry: "U.S. Mail Railway Post Office." Note the letter drop! This photo was taken along South Juniata Street, adjacent to the PRR's Freight Station. |
