Tube engineers work through night to fix concrete blunder

London tube engineers worked through the night to clean up freshly poured concrete that leaked into a signal control room causing the Victoria Line to close.

The incident occurred yesterday while Bam Nuttal contractors were working on the new Victoria line station in an area next to the Victoria line signal control room.

Nigel Holness, London Underground’s operations director said:”These works involved the use of water and cement which leaked into the room, damaging equipment.

“This has meant there are no signals working on the southern section of the line.”

However, this morning London Underground said engineers had now removed the concrete.

Peter McNaught, operations director for the Bakerloo, Central and Victoria lines, said: “Our engineers have worked tirelessly through the night and have successfully repaired the damaged signalling equipment.

“A good service is now operating across the Victoria line.

“We again apologise to our customers who were affected by yesterday’s disruption.”
