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:
“Life is a long Dardenelles, My Dear Madam, the shores whereof are bright with flowers, which we want to pluck, but the bank is too high; & so we float on & on, hoping to come to a landing-place at last—but swoop! we launch into the great sea! Yet the geographers say, even then we must not despair, because across the great sea, however desolate & vacant it may look, lie all Persia & the delicious lands roundabout Damascus.”
—Herman Melville (1819–1891)
“There is a small steam engine in his brain which not only sets the cerebral mass in motion, but keeps the owner in hot water.”
—Unknown. New York Weekly Mirror (July 5, 1845)
