Bert

Bert is a small blue tender engine who is the quietest and oldest of the Arlesdale Railway engines.

Personality
Bert is the quietest of the Arlesdale Railway engines. He appears to be very easy going and friendly. One thing Bert doesn’t like, however, is the idea that bigger engines (and some people) might look down on the little engines just because they’re small. Bert usually gets on with his jobs without complaining and doesn’t mind what kind of work he does as long as he’s treated with respect.

Basis
Bert is based on the Ravenglass and Eskdale Railway's River Irt.

Trivia

 * Bert uses Mighty's original whistle sound at a half-step higher in pitch.
 * Bert's rebuilt form has never been featured in either the Railway Series or television series.
 * In Sticking Power, Bert is said to be younger than Rex and Mike. However, Bert's basis was built long before the other two. Bert has also been stated to be the youngest on the Official Website. His own build date is currently unknown since there is no official evidence to state his actual build date.
 * In Bert's trading card promo, he is depicted as a 4-8-2 along with Rex and Mike.
 * From Jock the New Engine onwards in the Railway Series, as well as in the TV series, Bert is depicted with wheels outside his frames, contrary to his basis and his previous appearances. His valve gear was also changed.
