The Works are divided into three sections, Locomotive, Carriage, and Wagon, and together they cover an area of 323 acres, of which 73 are roofed. In addition to the construction and repair of locomotives,carriages, and wagons, a great variety of miscellaneous work was done at Swindon, including large quantities of cagtings, forgings, etc., for other departments and repairs to pumping and hydraulic machinery.
