The Railway Series

Prior to the events of Small Railway Engines, Sir Topham Hatt brought a Ballast Regulator to his railway. In 1967, he was used to haul and clear away ballast, and pack new fresh stones (from the Arlesdale Mines) within the trackbeds throughout the North Western Railway. During this time, he was usually seen working with Donald and Douglas.


Not much is known about Sodor Railway Repair's personality. However, his Wooden Railway box description, states he is a hard-worker that knows the true meaning of working on railways, and aims to make the rides safer and smoother for the engines.
