The Southern was definitely ahead of its time. We generally think of low bulkheads are being a very modern thing.
Note the very low bulkhead, Hydra-Cushion stencil, but still has ribbed-back wheels. One of 25 cars #d 115750-150774 rebuilt by Evans in 1964 from series 120998-122997, which were pulpwood "racks" rebuilt in 1956 from _gondolas_ in the series 175000-176344.
Stenciled as return to Rome, GA, so presumably this transformer came from the GE plant there.
49'9" over the pulling faces because of the cushioned underframe. Otherwise the body is a typical 40-foot fishbelly sidesill flatcar of the prewar years, even though they started life as low-side gons with straight sills.
