A two-month rebuilding project is to begin in November at London’s Blackfriars rail station.
The work is part of a £5.5 bn Thameslink scheme to introduce longer 12-carriage trains on its route between Bedford and Brighton.
The busy station on Thameslink’s central London route will be closed to passengers for eight weeks while the work is carried out between November 20 2010 and January 16 2011.
Engineering work is also scheduled to take place for a six-day period over Christmas on the central route between St Pancras International and London Bridge, closing that section of the line completely.
Thameslink work has been ongoing at Blackfriars Underground station since March 2009 and will continue until November 2011.
Every day, 5,400 people use Blackfriars national rail station in the morning and evening rush hours.
