PRR H-36 Hopper Car Production, #2 of 3, 1957

SRS. Here is a production-line photo of H-36 Hopper Cars taken at the Pennsylvania Railroad's Samuel Rea Shop in Hollidaysburg, Pennsylvania, during May of 1957. Shown here are machines which could turn an unfinished railroad car sideways and/or upside down so that welding could be done on a flat surface.
