Arthur is a large tank engine originating from the London, Midland and Scottish Railway. He runs the Norramby Branch Line.


When Arthur first came to Sodor, he took great pride in his spotless record. He soon lost it however, after colliding with Duck's goods train in an incident largely provoked by Thomas and Percy. However, this spotless record was soon amended, after Thomas apologised to him for causing the accident.


Arthur is a big tank engine who has never been naughty in his life. He was highly esteemed for his "spotless record" before he arrived on Sodor, never having made a mess or a fuss and never having caused an accident. His main duties were to shunt trucks and haul goods trains. However, after a jealous Thomas tricked Arthur into setting his standards too high with the trucks, his record did not stay as spotless as he had hoped. Arthur is very obedient, cautious, and well-behaved. He aims to please in his work and do everything as best he can. He now mainly runs the Fishing Route by the coastal village, a duty which Thomas was only all too grateful to be relieved from. Here, Arthur enjoys the sea air and the smell of the fish.


Arthur is painted LMS burgundy with gold boiler bands and yellow lining with the letters "LMS" written on his side tanks in yellow. Before he came to Sodor, he was painted in the LMSR' black livery with white lining.




  • According to an early leak on the names of the seventh season characters, Arthur was originally going to be called Clarence. It was then changed to Arthur, when TV mag ran a competition to give him an official name, and that was the one chosen. Arthur was named after the late grandfather of competition winner Luke Sharp.
  • Though he is painted in an LMS maroon livery, his class was only ever painted black when in service on the LMS.
