Isle of Wight Central No. 3 “Mill Hill”
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 The locomotive was withdrawn in 1913 and sold in 1918 to Holloway Bros.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.
