London's Fenchurch Street station just avoided closure on Monday after a loose cladding panel was found hanging over the tracks.
In the event only Platform Two had to be shut for the day, minimising train diversions.
Network Rail maintenance engineers waited until 11pm, when Essex commuter services close, in order to shut down station power lines and allow closer inspection of the loose panel over the platforms.
Welding on the 2m by 2m panel appeared to have been damaged at the base. The loose panel was bolted firm and the other panels checked. The panels make up the facia of a platform roof edge formed by the base of the Dartmoor Building which sits above the tracks.
