#OldStreet - Incident affecting the Northern City Line on Friday, March 8.
At 10:09, a train driver reported that water was flowing from the roof of the Moorgate Tunnel - between Old Street and Essex Road stations. Lines were immediately blocked and our response teams were sent to site.
At 11.05 our staff boarded a special empty train from Moorgate to investigate the problem. As the train approached the area at low speed, two large piling drills - which were being used above ground by a building contractor - penetrated the skin of the tunnel.
Repairs to the tunnel are ongoing but the line - which is normally closed at weekends - is expected to reopen in time for services on Monday morning.
