A coaling tower, coal stage, coaling plant or coaling station is a facility used to load
coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen.

County Durham, where coal drops were built by the
Stockton and Darlington Railway in 1847.
In time, railway companies constructed more elaborate coaling towers, made from wood, steel, or
reinforced concrete (ferroconcrete).
In almost all cases coaling stations used a gravity fed method, with one or more large storage bunkers for the coal elevated on columns above the railway tracks, from which the coal could be released to slide down a
chute into the waiting locomotive's coal storage area. The method of lifting the bulk coal into the storage bin varied. The coal usually was dropped from a hopper car into a pit below tracks adjacent to the tower. From the pit a conveyor-type system used a chain of motor-driven buckets to raise the coal to the top of the tower where it would be dumped into the storage bin; a skip-hoist system lifted a single large bin for the same purpose.
Some facilities lifted entire railway coal trucks or wagons. Sanding pipes were often mounted on coaling towers to allow simultaneous replenishment of a locomotive's sand box.
