Main Office Block of the Great Western Railway Works, Swindon
This building was originally the Chief Mechanical Engineer's and Drawing Office for the Great Western Railway works. The whole building is archaeologically and historically most interesting as the nerve centre of the GWR works, used by Gooch, Armstrong, Dean, Churchward etc. It is where the Castles, Kings, Warships and other important classes of train, both steam and diesel, were designed. The building also demonstrates the 3 main periods of the historical development of the works
