Aesthetics Virtual reality imaging and artists’ impressions of the redeveloped area at two levels around the new concourse bridge show an enhanced passenger circulation and retail environment, with new architectural features which will show off the 1990s International roof structure to great effect. It can also be seen from the imaging that the Victory Arch will be displayed far more effectively as part of the overall ambience than it ever has been previously. Another major structure to be incorporated into the redeveloped area of Platforms 20 to 24 is a new link roof, which will form continuous cover between the iconic International roof and the original station roof trusses. The structural glass wall, which previously separated the International from the domestic stations, was taken down as part of the modifications for the new concourse. Capacity demands Network Rail’s Wessex Route is one of the busiest and most congested parts of the railway network. In 1997, soon after privatisation, there were 108 million passenger journeys annually on the whole South West (Wessex) Route. Currently, that figure has more than doubled to 234 million per year. Furthermore, a baseline passenger survey study made in 2013 forecast that between that date and 2043 there would be an increase of 40 per cent. Those statistics refer to the whole SW (Wessex) Route. For Waterloo station alone, the statistics are perhaps even more significant. Here there are more than 99 million passenger journeys per year, up from 58 million in 1998. More people use Waterloo station than Heathrow airport. Capacity solutions To respond to these pressing demands for increased capacity, Network Rail and South West Trains, in partnership with the Department for Transport, have developed a strategy known as the Waterloo and South West Upgrade. The primary key components of this upgrade are:
