Trains are being delayed and cancelled across London this morning, as several train lines battle icy conditions and technical problems. 

Widespread delays are expected on Thameslink and Southern trains after a train broke down outside London Bridge. 

Delays of over 20 minutes are being predicted, and expected to last until midday.

Southern Rail have said tickets will be accepted on London Overground and Gatwick Express. 

And both Thameslink and Southern Rail are also reporting an "operating incident" at Norwood Junction causing delays to all trains to London Bridge. 

South West Trains are warning of delays between Wimbledon and Clapham Junction this morning due to a points failure, with speed restrictions in place. 

Earlier services from Wimbledon into London Bridge faced delays and cancellations this morning due to over-running engineering works. 

Meanwhile, dozens of trains have been delayed this morning due to icy conditions overnight, with a yellow weather warning in place until 9am this morning.
