The Cotswold Line is an railway line between and in England. History Early years The line between Oxford and Worcester was built under an 1845 Act of Parliament and opened in 1851 as part of the Oxford, Worcester and Wolverhampton Railway. The Act required the line to be built to Isambard Kingdom Brunel's broad gauge but delays, disputes and increasing costs led to its being completed as standard gauge. The first stage of the Worcester and Hereford Railway opened between Henwick and Malvern Link on 25 July 1859. The bridge over the River Severn was approved for traffic the following year, and trains started running through from Malvern Link to Worcester Shrub Hill station on 17 May 1860. A short extension from Malvern Link to opened on 25 May 1860. On 1 July 1860 the Oxford, Worcester and Wolverhampton Railway absorbed both the Worcester & Hereford Railway and the Newport, Abergavenny & Hereford Railway to form the West Midland Railway. On 13 September 1861 the final stage of the railway opened between Malvern Wells and Shelwick Junction. This junction is just north of Hereford station on the line between Hereford and Shrewsbury, and it finally created a through route between Worcester and Hereford. The Great Western Railway took over the West Midland Railway in 1863. The original tunnel through the ridge of the Malvern Hills, Colwall Tunnel, was completed in July 1860. However, the tunnel was unstable, and it was closed for short periods in 1861 and again in 1907 following rock falls. Eventually the GWR decided to build a new tunnel to the south of the existing one. This opened for traffic on 2 August 1926. The old tunnel was abandoned, and during World War II it was used to store torpedoes. In the early 1970s, 25 miles from Moreton-in-Marsh to Norton Junction, Worcester were converted from double to single track. Following serious floods, which washed parts of embankments away, the line was closed for about a fortnight during July and August 2007 for repairs. Improvement works 2008–2011 Network Rail completed the redoubling of of track from just east of to , and from to about west of Evesham on 22 August 2011. This was intended to improve reliability, enable non-stop operations and allow an hourly off peak service to run on the line. The Office of Rail Regulation approved the work in June 2008, although the planned work
