Network Rail has released this timelapse video showing the Waterloo works after six days. So far 1,000 engineers and track workers have laid 1,270 metres of track, demolished 376m of platforms to make way for new platforms and poured 230m of concrete. In total they have worked 60,000 hours.
NR has closed platforms 1-10 at Britain's busiest station, and the work is due to be completed on August 28. The work is being carried out 24 hours a day.
