Toby is a Great Eastern tram engine who works on Thomas' Branchline. He is good friends with Thomas, Emily, Rosie, Stanley, Mavis, Daisy and Percy. He is often seen with his coaches Henrietta and Victoria and his luggage van Elsie.
Toby was built by James Holden at GER's Stratford Works in Stratford, London, England in 1914 and originally lived at Great Yarmouth Docks, Norfolk with his brothers before working on an unnamed tramway. In 1951, Toby came to work at the quarry on the Ffarquhar Branch Line after his old railway in East Anglia closed, as it was found to be illegal for Thomas to go on the quarry tramway without sideplates or cowcatchers.
Toby is old and, at first, was teased by James for his shabby paint. James stopped calling him names after he crashed into some tar wagons and Toby was given chocolate-brown paint for his hard work.
Toby has two coaches named Henrietta and Victoria and a luggage van called Elsie.
