Trains between Norwich and Ely are still suspended after lightning struck a signalling system at Attleborough.

Greater Anglia has told passengers travelling between Norwich and Ely to check before they do so on Friday after the equipment was damaged during Thursday's storms.

Network Rail engineers are working to fix the signalling system, but it is unlikely to be completed until Friday afternoon, with disruption expected on the Norwich to Cambridge line to continue until 4.30pm.

When lightning strikes a rail, the high voltage can damage sensitive electronic signalling equipment. As the signalling system fails safe when a component is damaged, all signals in the area turn red and trains must stop.

Customers travelling between Norwich and Cambridge may travel via Stowmarket, and use Ipswich to Cambridge trains, or Ipswich to Peterborough, via Ely.

A limited bus replacement service is in operation between Norwich and Ely, connecting with Great Northern and Cross Country services between Ely and Cambridge.

A spokesperson for Network Rail's anglia route said: 'During an intense electrical storm on Thursday, lightning damaged signalling equipment on the railway between Norwich and Ely.

'We are replacing the damaged parts as quickly as possible and we are working closely with train operating companies to get trains moving again as soon as we can.

'We are sorry for the inconvenience this will cause and ask that passengers check before they travel.'

A Greater Anglia spokesperson added: 'Services are currently suspended between Norwich and Ely, owing to damaged signalling equipment which was struck by lightning.

'Network Rail is working with its suppliers to rectify the fault, however there will be no services between Norwich and Ely until further notice and customers are advised not to travel.

'We apologise to passengers for the severe disruption and inconvenience caused.'
