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


Thomas & Friends

Arthur took great pride in his spotless record, which he soon lost after colliding with Duck's trucks in an incident largely provoked by Thomas. However, this spotless record was soon amended, after Thomas apologized to him for causing the accident.

He was bought to shunt and pull goods, but then was transferred to the coastal run, on which he enjoys working. He is responsible for this line, which is famous for its fish. Arthur, along with Henry, Salty, and Porter, were the only engines known to enjoy the smell of fish.


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. Arthur can be a bit naive, however, and 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 all too grateful to be relieved from. Here, Arthur enjoys the sea air and the smell of the fish.

Technical Details


Arthur is based on a London, Midland and Scottish Railway (LMS) Ivatt Class 2MT tank engine developed for the LMS, (hence the initials on his tanks). Unlike his basis, Arthur lacks a sand dome.

According to Robert Gauld-Galliers' original artwork, Arthur was originally going to have the number 41241 painted in yellow on his coal bunker and a top feed like his original basis. The number 41241 comes from a preserved 2MT on the Keighley and Worth Valley Railway, though it is worth noting that this particular engine was built by British Railways and thus never worked for the LMS. Three other members of the class are also preserved.


Arthur is painted in LMS maroon with gold boiler bands and yellow lining. The initials "LMS" are painted on the sides of his tanks in yellow with red lining. His wheels are also painted red and his ladder is painted black while the steps at his front buffer beam are red and he has white lamp irons.


Magazine Stories

Arthur also appeared in the magazine stories, Arthur and Emily, Bright Sight, Shell Engine, Speedy Dennis, What a Whistle! and Whizzing Wheels.

Arthur also appeared in DVD Bingo.
