A major £9billion programme of rail investment is expected to create space for 120,000 extra daily commuters into London.
Transport secretary Justine Greening announced the scheme to improve the rail network and boost the economy today.
It includes more than £700million of investment in additional capacity around London and the South East, with a major refurbishment at London Waterloo to increase platform lengths.
Together with Crossrail, the programme plans to deliver more than 120,000 extra daily peak-hour commutes in and out of London by the end of the decade.
Prime minister David Cameron said: "From Crossrail, high speed rail and now the billions of pounds of investment we are announcing today, this government is committed to taking the long term decisions to deliver growth and jobs.
"In what is the biggest modernisation of our railways since the Victorian era, this investment will mean faster journeys, more seats, better access to stations, greater freight links and a truly world class rail network.”
Detailed plans will be published in January 2013.
