Originally a large number of trailers were railroad-owned, and loading and unloading was done circus-style by driving the trailers onto a string of flatcars from one end. A major advance came in the 1960s with the advent of the first side-lift cranes, dramatically speeding up loading and unloading. Today the combination of trailer and container shipments, known collectively as intermodal, constitutes the largest class of freight on American railroads.
