The spine cars are one of the most recognizable freight cars on the rails today. Named after their simple, spine-like appearance, these versatile cars carry anything from highway trailers, to international, corru-gated containers. Built in late 1997 by Trinity Rail for TTX, these 5-Unit Spine Car's feature TTAX reporting marks. While very similar to other 53' Trinity Spine Cars, the "RAF53C" class boasts nearly 250, 5-car sets on the TTX roster.
