RAIL passengers face major delays to their journeys this evening after hot weather damaged parts of the train network.
Due to signalling problems services trains are not running between Guildford and Havant.
It’s not yet known when normal services will resume.
Arrangements are being made for alternative transport to operate.
Local stagecoach buses will accept rail tickets between Farnham and Haslemere.
Trains between London and Havant/Portsmouth will be diverted via Basingstoke. These services aren’t calling at stations between Woking and Hilsea.
Customers travelling to Farncombe, Godalming, Milford, Witley, Liphook, Liss, Petersfield and Rowland’s Castle should travel to either Guildford or Havant where road replacement transport will be arranged.
Customers in the Portsmouth area can use Southern services to and from Havant and Bedhampton.
South West Trains tickets are valid on these services.
Meanwhile, engineering work is being carried out at London Waterloo station after part of the track was damaged by the hot weather this afternoon.
It means four platforms are not in use and services in and out of the station are either being cancelled or being delayed by up to half an hour.
The disruption is expected to continue until the end of the day.
A spokeswoman for the South West Trains-Network Rail Alliance, said: ‘We would like to apologise for the disruption our customers will face on their journeys home tonight.
‘As a result of emergency engineering work to fix a track defect, we are unable to use four platforms at Waterloo which is having a serious impact on the services we can deliver.
‘Because of that we will have to run an amended timetable for the rest of the day.’
‘Safety is our absolute priority.
‘We have no choice but to make sure these repairs are carried out before we can restore train services on these lines. We expect to run a normal service from tomorrow morning. We would like to apologise again to our customers for this and thank them for their patience.
