040 BMC

When the Thin Clergymen and the Fat Clergyman visited the Arlesdale Railway, they drove a purple car with the number plate "040 BMC", at one point they accidently drove through a puddle and muddy water splashed onto Bert while he was pulling a train full of passengers.

The car is based upon a Mark 1 Austin 1100, the letters "BMC" on the number plate are a reference to the British Motor Corporation, the manufacturer of the vehicle in question.

The car only appeared in the twenty-second book of The Railway Series, Small Railway Engines.
