Wessex Capacity Alliance –  Waterloo station

The Wessex Capacity Alliance is a collaboration between Skanska, Colas Rail, Mott MacDonald, AECOM and Network Rail to deliver a £400million programme of improvements at the UK’s busiest railway station, which will result in the biggest package of improvements for passengers travelling to and from London Waterloo for decades.


The investment will deliver a bigger and better London Waterloo including:

Rebuilding the former Waterloo International Terminal, allowing platforms 20-24 to be brought back into use with modern facilities, new track and signalling and a layout suitable for thousands of domestic passengers.Extending platforms 1-4 to allow longer ten-car trains to run to London suburban stations. This work requires the alteration of platforms 1–8, rebuilding the tracks and renewal of the signalling approaching the platforms.  All this work will take place during August 2017.Creating a spacious, modern and accessible station concourse near platforms 20-24.


The end result of the planned upgrade works will be a 30 per cent increase in capacity during the morning and evening peaks and significantly improved passenger facilities.


The Wessex Capacity Alliance is also delivering:


Improvements to Vauxhall station to relieve train and passenger congestion Improvements to track and rail systems along the Windsor lines
