Travel chaos as train derails on key UK line to major stations

'Do not travel' warnings have been issued

The three train operators have since issued 'do not travel’ warnings, as cancellations and delays of up to an hour expected until 1 pm.

The train derailed close to Selhurst Depot, leading to it blocking the lines towards Norwood Junction and London Bridge.

Fortunately, no one has been injured.

Additionally, a fault with the signalling system between Norwood Junction and London Blackfriars is also behind today's delays.

Impacted Southern services include:

• Epsom to London Bridge services suspended 
• Tattenham Corner/Caterham to London Bridge services diverted via an alternative route 
• Uckfield to London Bridge – a reduced service

Thameslink announced the following services are suspended:

• London Bridge to East Grinstead 
• Brighton to Cambridge 
• Bedford to Three Bridges
