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:
“I know a bank where the wild thyme blows,
Where oxlips and the nodding violet grows,
Quite overcanopied with luscious woodbine,
With sweet musk-roses, and with eglantine:
There sleeps Titania sometime of the night,
Lulled in these flowers with dances and delight.”
—William Shakespeare (1564–1616)
“Industrial man—a sentient reciprocating engine having a fluctuating output, coupled to an iron wheel revolving with uniform velocity. And then we wonder why this should be the golden age of revolution and mental derangement.”
—Aldous Huxley (1894–1963)
