Bill and Ben

Bill and Ben are tank engine twins who work at the China Clay Works.


Bill and Ben arrived on Sodor to work at the China Clay Works. At first, The Fat Controller sent them to work at the Harbour collecting trucks and taking them to the China Clay Works. One particular day when they were new on Sodor, they discovered that their trucks had gone missing, and there was a patch of oil in the place of where the train should have been. Confused and angry, the twins deemed the thief a "Diseasel" and came up with a plan to get their trucks back! The "diseasel" turned out to be BoCo and after they made up their mistake, Edward took away the naughty twins, for it is said that he is the only one who can handle him!


Bill and Ben are Sodor's mischievous saddle tank engine twins, who have great fun in teasing the other engines of the railway. Each has four wheels, a tiny chimney and dome, and a small squat cab. They often work in the China Clay pits and quarries. Their loads of clay can be used for many things such as paper, paint, and pottery. They take trucks for engines on the main line and ships in the harbour and are regularly seen around Brendam Docks. They enjoy attention and love taking visitors and being photographed. They tend to work together, like most twins, but even this youthful pair can have their arguments among themselves and can squabble with one another. They are highly prone to playing tricks and being cheeky. They have even teased Gordon on more than one occasion. Duck has called them "the bees" before, for being terrors when they start buzzing around. Edward and BoCo are the only engines who can really keep them in order enough to put a stop to their games and make them scamper along and behave. There is no real harm to them, but even Edward admits that they are maddening at times.


Bill and Ben are painted dark yellow with red lining. They both have brown nameplates with yellow writing, "SCC" written on their side tanks in yellow and "Brendam Bay" on the front of their saddle tanks.




  • A behind the scenes picture of Bill's model reveals that he and Ben were to have numbers on their smokeboxes above their faces, as they did in the Railway Series.
  • Ben's whistle sound is Thomas' in a higher pitch, and Bill's is the same in an even higher pitch. But often, throughout the CGI Series, they swap whistle sounds.
