This 57’ converted TOFC flat car is blue with white lettering and runs on Barber Roller Bearing trucks. Originally built in 1952 as a Department of Defense 103-W tank car and used to store isopropyl alcohol, it was stripped to its frame and rebuilt into a 70-ton spacer car in 1995. Because NASA rocket components are so heavy, empty spacer cars help distribute the weight of the train to comply with bridge and track load restrictions.
