TfL is upgrading the Piccadilly, Bakerloo, Central and Waterloo & City lines as part of the New Tube for London programme. Starting with the Piccadilly line, where modern signalling and trains will deliver 60 per cent increased capacity, TfL will begin to introduce new signalling and trains from the mid-2020s. A peak service of 27 trains per hour with air-cooled, walk-through Tube trains, providing a 25 per cent increase in capacity, will be introduced on the Bakerloo line from the late 2020s.

In advance of this, TfL is carrying out a programme of works to extend the life of the Bakerloo line fleet, ensuring these trains can continue to provide a good service until the line is modernised.

Bidders for the order of the new trains will be encouraged in their designs to demonstrate improved wheel-rail interface, which would have positive implications for rail wear and noise. In the meantime, London Underground's approach is to ensure that the track continues to be maintained to the highest standards. In particular, improvement work in the tunnel sections of the Bakerloo line will result in a more modern track form consisting of continuous welded flat bottomed rail on a base-plate, which is proven to minimise noise and vibration.
