There once existed a 55+1⁄2-mile (89.3 km) network of railway lines on the Isle of Wight, which operated both as a self-contained railway network, and as links to ferry services between the island and the South coast of Great Britain. The routes were opened by several companies between 1862 and 1901 and modernised after The Grouping in the 1920s. Most of them were permanently closed between 1952 and 1966, whilst the 8+1⁄2-mile-long (13.7 km) Island Line was temporarily closed in 1966 and rebuilt for electric train services, introduced in 1967. Replacement trains were introduced in 1990, and a major renewal is due in 2021.
