Bill and Ben are very cheeky twins who work at Cliffstone Centre Quarry.
Bill and Ben are the mischievous twins of the Cliffstone Centre Quarry crew! The two little engines, built to be low-slung, help take care of the rougher work in the busy quarry yards, like shunting or collecting cars from the mineshafts of clay and slate or hauling smaller trains between the quarry and the harbours. The two have great fun teasing the other engines and playing tricks on them, and do tend to squabble with one another, but they're hard workers deep down at heart...they just have a bit of a troublesome way of having fun!
Bill and Ben are based on the Bagnall 0-4-0STs "Alfred" and "Judy" of Par, Cornwall, who are both preserved and in working order at the Bodmin and Wenford Railway.
Alfred and Judy are painted in a green coat of paint, with yellow lining, although the former was once repainted in a yellow coat of paint, very similar to Bill and Ben's yellow coats of paint.
Bill and Ben both have brass nameplates with yellow writing, "SCC" written on both sides in yellow and "Brendam Bay" on the front of their saddle tanks.
