Copper haired coppers, Cooper & Cropper (try saying that after 8 pints) usually patrol the canal side at the beginning of their shift. Cooper secretly fancies Cropper, and to display his love, he likes to talk about the history of the various wagons, flange bolts, sleeper types, fishplates, bullhead chairs and rail spikes. But Cropper is far more interested in Ed the engine driver in charge of the throbbing Diesel engine.
