This afternoon our contractors were working on the new station in an area next to the Victoria line signal control room. 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.
The line is currently suspended between Warren Street and Brixton. Our engineers are working hard to resolve the situation as soon as possible to get services back up and running, but the line is expected to be affected for the remainder of the day while repairs are carried out. I am sorry for the delays which will result and I would ask that passengers seek alternative routes on the Northern and Bakerloo line.
