Class	Star

The Great Western Railway (GWR) Star Class of 2-2-2 broad gauge steam locomotives were used for passenger train work. Designed by Robert Stephenson, the class was introduced into service between November 1838 and November 1841, and withdrawn between April 1864 and September 1871.

A total of twelve Star Class locomotives were manufactured. Notably, they were given the romantic or colloquial (rather than scientific) names of astronomical bodies. By the time the last had been delivered, GWR engineer Daniel Gooch had designed and taken delivery of several of his larger Firefly Class.

A non-working replica of North Star was constructed for the 1923 Cavalcade, and is now housed at Swindon Steam Railway Museum.

It made use of some of the parts of the original North Star, scrapped as recently as 1906, but is not capable of being steamed. Although it featured in the railway's centenary film in 1935, it was pushed by another locomotive.
