The multi-million pound redevelopment of Waterloo train station could begin as early as October after the station submitted a planning application to local authorities.
The plan, which is now subject to approval from Lambeth council, will see five new platforms installed and a complete redesign of the stations concourse and existing platforms.
Following preliminary work, construction could commence at the site in November 2015, with completion by the end of 2016.
Part of the work will see platforms 20-24, once part of Waterloo’s international terminal, converted for the use of domestic trains.
Associated track and signalling work would then continue on the lines until mid-2017.
The work is part of an overall programme to increase capacity by 30 per cent at the UK’s busiest station.
In addition to the work outlined in the latest proposal, there are also plans being developed to extend platforms one to four, paving the way for 10-car trains to run on the suburban network for the first time.
Commenting on the news, Network Rail’s infrastructure director John Halsall said: “The project to improve the railway and strengthen the bridges on the approach to Waterloo is an absolutely vital part of our plans to improve capacity at Britain’s busiest station.
“The submission of the planning application to carry out this work is an important step forward and, if approved, we expect to start work before the end of the year.”
South West Trains managing director Tim Shoveller said: “We operate one of the busiest railways in Europe, with over half a million passenger journeys every day.
“The biggest investment for decades on our network is well underway but the work to expand London Waterloo is absolutely vital to make sure we can provide much needed extra space, both for our customers now and in the future.”
