Network Rail and South Western Railway have apologised after tens of thousands of passengers faced yet more delays on the lines to Waterloo this morning.
A signal problem at Woking halted services.
It’s the latest in a series of problems causing disruption on the line.
The main lines from Portsmouth, Southampton and Basingstoke were worst hit.
Meanwhile, passengers will be able to meet senior managers to express their concerns over recent poor performance at Waterloo during Thursday evenings rush hour.
In an alert sent to SWR customers, it said the disruption is expected to last until midday.
The rail company has said tickets will be accepted, at no extra cost, on the following services:
- Basingstoke to Reading on Great Western Railway Services and Cross Country Services
- Reading to London Paddington on Great Western Railway Services
- London Underground between London Paddington and London Waterloo by any reasonable route
- Southern Rail services between Dorking and London Victoria
