There are a number of major railway lines running through the county, including the Welsh Marches Line, the Heart of Wales Line, the Cambrian Line, the Shrewsbury to Chester Line and the Wolverhampton to Shrewsbury Line, as well as heritage railways including the well established Severn Valley Railway. The Cambrian Heritage Railway exists in Oswestry. The three train operating companies working in the county are West Midlands Trains, Transport for Wales and Avanti West Coast. A new company, Wrexham & Shropshire, commenced services from Shropshire to London Marylebone, in spring 2008 but the service was discontinued on 28 January 2011 leaving Shrewsbury without a direct link to the capital. Virgin Trains (the operator at the time) recommenced services from Shrewsbury to London Euston on 11 December 2014, having withdrawn them in the late 1990s.
