Baz and Bernie are two crooks from The Mainland who visited The Technology Fair.


Thomas & Friends

Baz and Bernie first arrived on Sodor onboard Sonny, looking to steal an invention from the Technology Fair. By disguising themselves as cooks, they managed to infiltrate Ulfstead Castle.

Following a few mishaps with the other inventions, Baz and Bernie decided to steal the plans to Ruth's Hover-Car. Due to Sonny's disobedience, the pair chose to use Kenji as their getaway vehicle. During the escape, the pair were separated when Bernie removed Kenji's coupling and was left stranded on the passenger coach.

Baz was eventually caught by Thomas, Rebecca, Sir Robert Norramby, Ruth and the police and - after Bernie caught up and accidentally revealed their plans - the pair were arrested and taken away by the police.


Both Baz and Bernie are mischievous crooks. Out of the two, Baz is the more intelligent, often having to stop the rather simple-minded Bernie from spilling their secret plans. Baz is noticeably more villainous compared to Bernie, willing to force Sonny to help them by threatening to scrap him and willingly abandoning Bernie to get a bigger share of the profit. Baz was also willing to blame Bernie for everything to avoid getting arrested. Bernie is also the more naïve of the two, as he tends to miss a few key details or state the obvious. Additionally, he is loose-lipped in many critical situations.


Baz is the taller and more slender of the two. He wears a light grey shirt with a dark grey jacket, matching his hat and trousers. He also wears a blue tie with red spots and brown shoes.

Bernie, meanwhile, is rather stout. He wears a light brown coat with a white shirt, dark brown trousers and shoes and a pink neckerchief.
