Prototype Notes (Collector Deep Dive)

By the late 1950s railroads shifted new-car delivery from boxcars to open auto racks. During the late ’60s/’70s, Trailer Train (now TTX) standardized 85' flats fitted with bi- and tri-level racks; the RTTX marks identify auto-rack flats. The C&O “For Progress” shield reflects the road’s modern image before its Chessie/CSX era. Lionel’s short O-27 version captures that look in a layout-friendly length that runs anywhere.
