Isle of Wight Central No. 3 “Mill Hill”

Great Britain 1870 1 produced
State after the rebuild where a cab was added Locomotive Magazine, December 1921

One of the founding members of the Isle of Wight Central was the Cowes and Newport Railway that had been established in 1859 and operated a 4.5 mile line to the north of the line along the River Medina. In 1970 Black, Hawthorn & Co. in Gateshead-on-Tyne built a small tank locomotive with a saddle tank, which was later to be number 3 in the combined railway company.

After the Medina Wharf was built in 1877 and 1878, the locomotive spent much of its life there as a shunter. Later it was rebuilt, where the simple weather protection was replaced by a complete cab. When passenger service with steam rail motors was opened up for Medina Wharf staff, the “Mill Hill” was used along with a twelve-wheel passenger car as backup. The locomotive was withdrawn in 1913 and sold in 1918 to Holloway Bros. who operated a dock at Middlesbrough.
