Flat Car - Trailer-on-Flat Car
PRR #475209
PRR class F30A flat cars were one of the most numerous classes of flat
cars on that railroad with 1500 being built between 1933 and 1934. The
PRR utilized a massive one-piece steel casting on these cars, and that
sturdy construction meant that many lasted an incredibly ling time. The
cars were so successful that the PRR built another 250 nearly identical
copies in 1951, classified as F30D. Starting in 1954 the Pennsy converted
many F30D flat cars into early piggyback service cars. These cars received
perforated side rub rails, end loading ramps and four side posts. Eighty-six
cars were transferred to the new Trailer Train Company (TTX) between 1957 and
1958. These cars received additional upgrades in the form of ACF trailer
hitches and revised side rails and upgraded end ramps. The TTX cars also
received roller bearing conversions on their trucks. Classified as F30G, these
cars were used by TTX into the 1980s, many being upgraded with full roller
bearing trucks and many even painted in TTX’s yellow scheme.
