Edward Salmon, The Strand Magazine (1892)
“ When a train of trucks is full, an engine is attached to it, and away it goes over a viaduct some hundred yards long into a retort-house. If not deposited there for use, the coal is carried through it, across a connecting viaduct, to another house, and so on through half-a-dozen houses if necessary. There are a dozen retort-houses at Beckton, to say nothing of one now building which is to be the largest in the world, and from every one of these, engines and a string of trucks pop in and out like serpents at hide and seek. ”
