Island Line Trains is a train operating company which runs the 8 1⁄2-mile Island Line on the Isle of Wight. Island Line is part of South West Trains, a rail franchise in the United Kingdom owned by Stagecoach.
The name Island Line first came into use in 1989, when Class 483 trains were introduced on the route. This new brand name and a logo were included on the trains' livery. However, this re-branding did not officially occur until 1994, when it had completely replaced all RydeRail branding. From 1989 until 1996, Island Line existed as a sub-brand of Network SouthEast. In 1996, passenger services on the line were privatised as the Island Line franchise, with the winning bid from Stagecoach (legal name Island Line Limited). On commencing operations on 13 October 1996 the name Island Line for the passenger service was retained.
