“The controllers of these diesels do not move⟳ round in notches, so that the driver's only sure guide⟳ to the way in which he is working his locomotive is his ammeter, corresponding in a way to the steam-chest pressure gauge of a steam locomotive. When the diesel was being worked full out, the ammeter normally showed about 1,500-1,600 amps, with occasional surges of current at starting or up the steepest gradients to 1,700 or even 1,800 amps.”
