The engine or carriage to be transferred is brought to rest wholly upon one table, which is then turned a quarter round, and the carriage is then wheeled on to the next turntable, which being likewise turned a quarter round, the engine or carriage will then be in a position to proceed on the line to which the second table appertains."; "Of locomotive interest was "an engine house for spare engines which was about 60 ft. × 51 ft.; on the outside of this was an immense turntable sufficient to turn the engine and tender at once.""; "The domestic coal depot at St Pancras, north of Somers Town Goods.
