couldnt find anything over a take over only found stuff like this:
Redhill-based Balfour Beatty Rail has won a five-year contract to carry out track renewal work in partnership with London Underground.
The total value of the work to be delivered by the partnership is £220m, of which around half will be Balfour Beatty's share.
The works will include the replacement of ballasted track, points and crossings, including all ancillary signalling and drainage works on the Tube network.
Ian Tyler, chief executive of Balfour Beatty, said: "We are very pleased to be part of such a crucial project, working in partnership with London Underground to deliver a world-class transport system for London."
Works are expected to start in the spring and there is an option to extend the contract for a further two years after the initial five-year period.
The business works on all types of rail operation worldwide including high-speed passenger, freight and mixed traffic routes, dense commuter networks, metros and light rail.
