A burst water main on January 23 caused major flooding in a tunnel between St Pancras International and Farringdon, leading to services being cancelled on the route.
At 1500 on January 25, the water in the tunnel was at a depth of three feet, despite Network Rail’s efforts to pump the water out. Services are not expected to resume through the area until at least the end of today (January 26), while the burst main is repaired.
A Govia Thameslink Railway spokesman said: “A burst 16-inch water main will continue to affect our services until Thames Water can fix it. It’s safe for us to run our trains through the water as long as Network Rail can keep the flood levels down to a manageable level with pumps, but we have to run a reduced service.
Today, a reduced service is running on the Bedford-London route and Sevenoaks, Sutton and Brighton-London routes.
