Formed in 1974 as a subsidiary of Trailer Train Company (now TTX Company), Railbox did for box cars what Trailer Train had done earlier for piggybacking: established a pool of cars that could be used by all member railroads, without the burden of routing rules that prioritized empty cars for return to their home railroad. With its slogan of “Next Load, Any Road!”, Railbox strove to minimize empty backhauls and keep loaded cars flowing wherever needed, throughout the U.S., Mexico and Canada.
