Rail passengers travelling between Norwich and Ely are advised to check before they travel today (Friday, July 7) after signalling equipment was damaged by lightning.

Greater Anglia is running an hourly service between Norwich and Ely, but passengers for Cambridge are advised to travel via Stowmarket.

Network Rail engineers are currently working to fix equipment damaged by the electrical storm and the service is expected to return to normal from 7pm.

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.

We are replacing the damaged parts as quickly as possible and in the meantime we've opened the line with manual signalling in place so that some services can run. We are sorry for the inconvenience this will cause and ask that passengers check before they travel.'
