To achieve this, new track and infrastructure has been added – including a major new railway junction called Bermondsey Dive Under.
The new junction enables each train service to have its own dedicated line into London Bridge station. Southeastern trains travelling from Kent to ‘dive under’ the Sussex lines used by Southern and Thameslink trains, relieving the bottleneck in this area.
Previously this historic section of track, which dated back over 150 years, featured some of the most complex track layouts around – contributing to delays in and out of the station. The new infrastructure added will make journeys more reliable for millions of passengers travelling to and through London Bridge.

Construction: four years in 90 seconds
Work on the Dive Under began in Spring 2012 and was completed in December 2016. The first passenger train service ran through the new junction on 3 January 2017.
As part of the works, 20 bridges between New Cross and Waterloo East were also strengthened to cater for a Tube-like service of trains every 2-3 minutes through central London.
