Bear (originally known by his number, Diesel 7101) is a mixed traffic diesel engine who works on the Main Line. His name comes from the growling noises his engine makes, which make him sound like a bear.
Bear was originally known as D7101, and came to Sodor on loan with another diesel named D199. His companion was blatantly arrogant, and bad-mouthed the steam engines. Vulgar noises greeted this, until Duck and D7101 managed to shut up D199.
The next day, 7101's injector failed while pulling "the Limited". Henry, who was already towing 199 and his train of oil tankers, came to help; 7101 was still able to move by himself with some help from Henry. To the passengers' delight, Flying Scotsman took their train, while Henry helped 7101 home. Along the way, Henry told the diesel about his failed regulator. 7101's opinion of steam engines was greatly changed after the incident.
The engines persuaded Sir Topham Hatt to let 7101 stay on the North Western Railway, and renamed him "Bear." Bear liked this name, saying it meant he "really belonged." Even James, who was the last to accept diesels, could not help but like him. It later was revealed Bear pulls the Express when Gordon, Henry and James are busy. Bear also did Henry's duties while Henry was at the Works.
Bear is one of the more polite, charming, respectful, useful diesels. He is a loyal, friendly, and sympathetic sort, but he is extremely noisy and obstreperous, as he often makes unusual growling noises much to the disturbance of the other engines; thus earning the name "Bear." The Fat Controller was impressed with BoCo and Bear; he called them "versatile" because they could pull both coaches and trucks. BoCo and Bear usually defend the steam engines when a visiting diesel boasts about how superior they are.
Bear is based on a BR Class 35 "Hymek" Bo-Bo. His initial number, 7101, is an in-joke: the Class 35 was only numbered up to 7100. As Beyer Peacock Ltd. were the only company to build the Class 35, all were built in numerical order. Therefore it is safe to say Bear was built after D7100, who entered service 5 February 1964.
Bear is painted in the British Railways' Brunswick green livery with a narrow band of lime along the bottom of his sides, cream window surrounds and yellow warning panels. His number is painted on his cab sides in white. When he first arrived on Sodor, he was painted in the British Railways' Rail Blue livery with yellow warning panels. His original livery was used for both merchandise ranges he was released in.
