“Extensive damage to 500 metres of overhead electric power lines last night stopped trains running between London Paddington and Reading and Heathrow this morning. We were able to resume a limited service from midday.
“We have been working all day on our plan to replace the electric lines and associated equipment quickly and safely. We have been doing as much as possible away from the track, but we can only carry out repairs in earnest when trains are not running. We will wait until after the evening rush hour and begin work on the track at 21.15 tonight to install the new wires, before trains start running again at 05.00 Thursday 18th October.
“The extent of the damage means we will not be able to complete our repairs in one night, so while services on Thursday morning will be significantly improved, there may still be some disruption. We advise passengers to continue to check with train operators before travelling. We apologise to passengers who have been affected by this major incident.”
