The Tyne and Wear Metro Rolling Stock or British Rail Class 994 serves the Tyne and Wear Metro, a metro system in North East England, serving Newcastle upon Tyne, Gateshead, South Tyneside, North Tyneside and Sunderland. Since the inception of the Metro the rolling stock has remained the same. The fleet has been refurbished a number of times, with various liveries. Full refurbishment of the fleet is to take place from 2010 until 2015. Metrocars are to be refurbished by Wabtec Rail at its Doncaster facility with the main goal of the project to extend their service life until 2025.
