The Moseley Railway Trust’s extensive collection of narrow gauge locomotives includes many built by the company of Motor Rail, who were based in Bedford. Like many (all??) successful engineering businesses, Motor Rail understood the value of a robust and standardised product. Hence, their locos tend to have a strong family resemblance to each other. That said, they were not averse to building something a tad different from time to time. Once of these was the 12/20HP petrol engined locos, of which 28 were built as a design of lightweight petrol locos. Unlike the vast majority of Motor Rails, they did not use a Dorman engine. Instead, they were fitted with Austin side valve four cylinder petrol engines.
