rail users are advised to check before they travel due to major engineering works at Guildford over two weekends in April and on two Sundays in May.

Network Rail is investing £800,000 to renew important sections of track to make journeys more reliable.

Guildford is one of the busiest stations in the south of England with 8.2 million passengers in 2015/16, and the lines through Guildford are used heavily by services connecting Waterloo to the south coast.

Network Rail’s “orange army” will be replacing key sections of switches and crossings, as well as more than 200 metres of track, just to the south of the station platforms. The upgrades will take place over the weekends of April 1 and 2, and April 8 and 9, as well as on Sunday, April 30 and Sunday, May 21. Replacement bus services will operate during these times.

Network Rail director Becky Lumlock said: “As part of our upgrade plan, we’re investing £800,000 to make the railway at Guildford more reliable.

“This is an important part of our commitment to provide a better railway to the growing numbers of passengers. I’d like to thank passengers for their patience while we complete our upgrades, and remind them to check before you travel to avoid unnecessary delays.”

Network Rail will also be undertaking follow-up work overnight from Monday to Thursday during the weeks commencing April 3 and 10, and May 1 and 22, but this will not impact services.
