| Electric M.U. Here is an original photo that I took in Hollidaysburg, Pennsylvania, on 3 July 1965. Shown here is a close-up of Pennsylvania Railroad car #4533, an MBM-62T (Mail Car) built by American Car & Foundry: "U.S. Mail Railway Post Office." Note the letter drop! Photo taken along South Juniata Street, adjacent to the Freight Station. |
