A bank engine (United Kingdom/Australia) (colloquially a banker) or helper engine or pusher engine (North America) is a railway locomotive that temporarily assists a train that requires additional power or traction to climb a grade (or bank). Helpers/bankers are most commonly found in mountain divisions (called "helper districts" in the U.S.), where the ruling grade may demand the use of substantially greater motive power than that required for other grades within the division.

Famous quotes containing the words bank and/or engine:
“A man’s labour is not only his capital but his life. When it passes it returns never more. To utilise it, to prevent its wasteful squandering, to enable the poor man to bank it up for use hereafter, this surely is one of the most urgent tasks before civilisation.”
—William Booth (1829–1912)
“The will is never free—it is always attached to an object, a purpose. It is simply the engine in the car—it can’t steer.”
—Joyce Cary (1888–1957)
