South East upgrade

After investing £1.25bn to improve the railway in Kent and South East London between 2019 and 2024 our work to modernise the network for passengers continues with a planned £1.35 billion investment over the next five years.

The funding will tackle historic under-investment in the Kent network, replacing ageing equipment with new and more reliable technology to support improving train performance and keeping people moving for decades to come.

Keeping you on the move

Record investment means that we’ll be doing more work to improve the railway than ever before.  We’ll do most of the work when trains are not running,  but will need to work at weekends and on bank holidays.

If you are planning to travel at the weekend or on a bank holiday, please don’t get caught out.  Always check before you travel at National Rail enquiries or with your train operator, Southeastern or Thameslink.
