Bio
The Blisters were built in 1932 with open-sided cabs for a 2-inch gauge. When they arrived on Sodor in 1985, the volunteers of Arlesdale used parts to rebuild them with two 2-cylinder 12 h.p. Lister engines to rebuild them to a 15-inch gauge. They were repainted and fitted with a new cab and bonnet, in the style of a Lister Blackstone RM2. In 1989, they were refitted with two 20 h.p. Lister engines to improve performance.

Both have full electrics, radios and air brake systems for working light passenger trains in emergencies.

They are used for maintenance and shunting duties and were originally brought to the line for construction.

Basis
The Blisters are based on the Ravenglass and Eskdale Railway's Cyril. Their trouble starting is based on the trouble experienced with the Muir-Hill Fordson granite tractors that worked at Ravenglass with stone traffic until 1953.

Livery
Blister I and Blister II are painted black with wasp stripes on their fronts.

Appearances
