Stunning night time footage at the foot of the Shard shows the installation of a 30m signal gantry on the approach to London Bridge station.
As the clocks went back last weekend, over a hundred Network Rail engineers took advantage of the extra hour to install a huge new signal gantry that spans 10 of the 11 tracks on the approach to London Bridge station.
Network Rail is completely rebuilding London Bridge station over the next three years as part of the £6.5bn Thameslink Programme.
This Christmas and into the New Year period, when passenger numbers are at their lowest, parts of the station will be closed for 16 days to allow engineers to return to the site to finish the job by attaching new state-of-the-art signalling equipment. Replacing the current system, which has been in use since the 1970s, will dramatically improve reliability on one of the most congested railway lines in Europe and allow more trains to run through to central London and beyond.
