The Bletchley Flyover is a reinforced concrete railway viaduct that carried the former Varsity line over the West Coast Main Line in Bletchley, England. It was retained when the line closed and, as of July 2020[update], is being restored for use in East West Rail.
Construction
The structure is composed of 37 concrete spans,[1] resting on concrete piers. It is 605 metres (1,985 ft) long.[2] Most of the spans are beam-shaped; two are double-length arches.[citation needed] Electrification pads were provided when the flyover was first built, despite there being no plans to electrify the line.[citation needed]
History
In 1959, the Bletchley Flyover was opened to carry the Varsity line over the West Coast Main Line as part of the British Rail Modernisation Plan.[3][4] The plan proposed to develop the Varsity Line as a freight link from the East Coast ports to South Wales, capable of handling up to 2,400 wagons of coal class traffic and empties daily.[5] However, following the rejection of the Swanbourne sidings plan by Gerry Fiennes (Chief Operating Officer for British Railways, 1961–1963),[6] the line saw little use, with most freight traffic taking other routes.
In his 1967 book I tried to run a Railway, Fiennes described the little-used flyover as
The Bletchley flyover remains as a memorial to those who failed to see that railways must live by concentration and not dispersal.
— Gerry Fiennes, 1967[6]
The Varsity line closed to passengers on 1 January 1968; it remained open to goods traffic until October 1993,[citation needed] when the bridge was mothballed.[7]
The flyover was returned to use in 2006 along with a mile of track west of Bletchley to a loop at the Newton Longville Brickworks landfill site.[8]
2020 renovation
This section needs expansion. You can help by adding to it. (July 2020) |
As part of the East West Rail project that will reopen the Varsity line route, work to replace 14 of the spans began in April 2020.[9][10][11] Sections beside and over the WCML were removed in April and May.[12][13] The arches crossing Buckingham Road (on the east side of WCML) started being removed on 5 July 2020.[14] As of August 2020[update], the work is ongoing and are planned to include replacement of the remaining spans over the WCML.[12]z
The renovation will allow two elevated platforms to be added to Bletchley station.[15]
