SOUTH West Train services to Waterloo were delayed by up to two hours on Monday evening due to a “major power supply issue”.

Services continued to be delayed by up to an hour until Tuesday evening and no trains ran between Haslemere and Havant from midday on Tuesday until after 3pm.

A replacement bus service ran between Guildford, and Haslemere and Havant and Haslemere, as engineers worked to fix the fault with the signalling that had caused the problems.

A SWT spokesman said on Tuesday: “A major signalling power supply issue yesterday evening affected a large number of our services until the end of service last night, particularly between Guildford and Haslemere.

“Our engineers are still working to resolve these ongoing issues, however some morning services will be affected between Havant and Haslemere in both directions.

“The signalling problem means that fewer trains than normal will be able to run between Havant and Haslemere, and we have had to divert a number of services via Eastleigh this morning.

“Some of our fast services between Havant and Guildford will make additional stops in their journey to provide a service to stations affected by trains that have been diverted.

“A limited replacement bus service has been arranged between Guildford and Havant, and these will be running to support the train service from 7.30am.”

Rail services were also affected by a widespread power cut in parts of Surrey on Monday night, due to a fault at an electrical substation.

• A UK Power Networks spokesman told The Herald on Tuesday: “A fault at a UK Power Networks electricity substation resulted in a brief voltage dip seen by some of our customers between Guildford and Weybridge at 9.38pm yesterday.

“We’re investigating the cause and apologise for any inconvenience caused.”

• Services through Haslemere were delayed by 15 minutes last Thursday evening after someone was spotted walking on the railway lines near the station.

SOUTH West Trains hopes to join forces with Hoppa to provide a shuttle bus service from Woolmer Hill to Haslemere station, to minimise disruption while the car park is shut.

The car park closed on Monday and is due to remain shut until December, while a new deck for 100 more spaces is built.

SWT has been in discussions with passengers and other intererstecd groups over alternative ways of travelling to the station, and 100 parking spaces have been secured at Woolmer Hill, behind the Edge Leisure Centre.

Anyone interested in using a shuttle bus to the station can register their interest at the station ticket office from Monday.
