Bank Engine

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 self is, by its very essence, a being with a past. One must look lengthwise backwards in the stream of time in order to see the self, or its shadow, now moving with the stream, now eddying in the currents from bank to bank of its channel, and now strenuously straining onwards in the pursuit of its chosen good.
    Josiah Royce (1855–1916)

    The machine unmakes the man. Now that the machine is perfect, the engineer is nobody. Every new step in improving the engine restricts one more act of the engineer,—unteaches him.
    Ralph Waldo Emerson (1803–1882)
