The electrogyro locomotive

Toy cars propelled by energy stored in flywheels are well known. A rather more sophisticated form of this principle has led to the development of electric locomotives which require neither batteries nor overhead wires or conductor rails. The National Coal Board are interested in the possibilities of this system for underground transport. This article, which describes the construction and operation of an experimental locomotive, is based on a lecture delivered to a joint meeting of the Southern Centre of The Institution and the Southern Branch of The Institution of Mechanical Engineers on the 19th November 1959.
