WATER TROUGHS. Ramsbottom, the inventor of the eponymous safety valve, also invented the water trough. ( Known as track pans in the USA). By enabling the locomotive to pick up water whilst moving, they eliminated, or reduced, the need to stop for water and thus improved journey times. Of necessity, they would have to be situated on a level piece of track, and this should, preferably, be in a location where the line rose at each end, so that the scoop would move down into and rise out of the trough in accordance with the gradient profile. The length could be of the order of ¾ to 1 mile, and typically, during 50 seconds at 50 mph, a locomotive would pick up 2,000 gallons of water.
