Jupiter

Jupiter is another Robert Stephenson and Hawthorn Ltd. product. It was built in 1951 and was one of a batch of nine locomotives for Stewart and Lloyds Ironstone Mining Co. Ltd. of Corby. The design of these locomotives was similar to the Austerity saddle tank, the main differences were smaller diameter wheels and a shorter saddle tank which gave them a rather ungainly appearance, but with a tractive effort of 26,500 lbs they were capable of hauling very heavy iron ore trains. Jupiter began it's career at Gretton Brook Quarry but was later moved to Market Overton Quarry and then Buckminster Quarry from where it was purchased for preservation in 1970.

Jupiter was moved to the East Anglian Railway Museum and was offered for sale again in 1985. The Colne Valley Railway Preservation Society was successful in purchasing Jupiter and it went into service immediately after arrival at Castle Hedingham.
