On Friday night, 10 platforms at Waterloo station closed down for three weeks. This timelapse video, created by Network Rail, shows the final trains leaving these platforms before a fluorescent army of workers moves in.
Work will take place 24 hours a day for 24 days, with 1,000 engineers working on extensions to four platforms, and modifications will take place on others, so that longer, more modern, trains will be able to stop at the station.
Over the next 24 days, 1,000 engineers and track-side staff will be working shifts 24 hours-a-day to build extensions onto platforms 1-4, and to modify platforms 5-8, so that the newer trains can run from December 2017.
Becky Lumlock, route managing director at Network Rail, said:
This is an important day for the rail network as we reach a crucial stage in one of the most complex and significant engineering projects ever delivered at Waterloo, our nation’s busiest station.
As of the morning of 7 August, the expected chaos has failed to materialise, suggesting that those repetitive announcements you've been sick of hearing have done their job.
