Bio
Bill and Ben were brought to help at the Sodor China Clay Works. One day, they found that the trucks of clay were missing. Their drivers took of their nameplates and found the Diesel at Wellsworth. One twin would hide while the other would come up to him. He soon made him dizzy, but Edward came and sorted out the mess. Bill and Ben apologized for being rude and the diesel introduced himself as BoCo. Bill and Ben like to play tricks and get up to naughtiness. They've also been known to argue a lot.
