Network Track Record

摘要

THE first phase of Network Rail's programme to upgrade 25kV AC power supplies on the East Coast Main Line (ECML) is on track for completion in time for the introduction of new train fleets in 2018. Power Supply Upgrade Phase 1 (PSU1) isa £237million scheme to modernise and uprate traction power supply between Wood Green in north London and Bawtry, south of Doncaster. It will allow Virgin Trains East Coast and Thameslink Great Northern to introduce enhanced timetables and new trains in 2018/19. The work includes the installation of seven new sub-stations at Potters Bar, Welwyn, Langley Junction and Corey's Mill, near Stevenage, Hitchin, Little Barford and Essendine, near Stamford, where a new 400kV National Grid supply has been installed. Eleven other sub-stations have been replaced, five more refurbished, more than 600km of new cabling and 110 foundations laid, and a disused sub-station at Tallington, north of Peterborough, has been removed, saving £3m.
