Work to extend platforms 1 to 4 at London Waterloo has already come a long way only a week into the £800m upgrade at the UK's busiest station.

This footage, released by South West Trains , shows Network Rail's "orange army" working round the clock to ensure the works are finished by August 28.

Ten platforms at Waterloo have been closed since Saturday August 5, causing havoc for the thousands of commuters who use the station.

Around 113,000 people commute into Waterloo during the morning rush hour between 8am and 9am.

Commuters have reported that most morning journeys have been relatively smooth, despite the drastically reduced service.

London Waterloo has been crowded in the evenings

However, the evenings have seen Waterloo's concourse become severely crowded while a series of signalling problems, points failures and trespassers (both human and swan) have caused trains to be delayed by up to 30 minutes on some days.

On Wednesday evening (August 9), rain even began to seep through the roof of the 6.18pm service from Waterloo to Woking.

Network Rail has been handing out free ice cream and bottled water to ease the pain for commuters during the evening rush hour.

More than 1,000 engineers and rail staff are working on the upgrades, which will extend Waterloo's platforms by 30%, allowing for 45,000 more people to use the station at peak times.
