Top and tail
From Wikipedia, the free encyclopedia
A Top and tail train is a train with locomotives at both ends, for ease of changing direction. This is a UK term.
It is properly distinct from a push-pull train, which has a locomotive at one end and a control cab at the other end.
Trains going up zig zags of the Khyber Pass are Top and Tailed, although Pakistan Railways calls this by a different term.
