A problem with the electrical supply is causing disruption to journeys between Epsom Down and Sutton this morning (April 3) suspending and cancelling all trains.

Southern rail announced the problem on Twitter and notified passengers that 'all lines are blocked'.

Ticket acceptance has been in place on all TFL buses between Epsom Downs and Sutton and routed tickets will be accepted via Tattenham Corner and Epsom.

It was established that this morning a power supply issue between Banstead and Epsom Downs was discovered which has now been fixed. 

Southern have said that all lines are now re open but there will still be cancellations or delays up to 10 minutes.
