According to South Western Railway there is expected to be major disruption at London Waterloo station until at least 12 midday after engineering works on a large-scale upgrade of the station overran.
Passengers are advised to check before travelling. In a statement issued by Network Rail earlier this morning, it was said that only early passenger trains would experience delays.
"The upgrades taking place at Waterloo station are some of the biggest and most complex engineering projects ever undertaken on the railway.
"We are entering the final stages of that programme and are preparing the railway and station for trains and passengers.
"During the process of testing the complex signalling, we identified an issue in this safety critical system, which we are working to resolve. This will take some time to fix and a small number of early passenger trains may be delayed as a result.
"We are working hard to minimise delays to passengers, but safety is our number one priority."
