Network Rail was the second largest client for the construction industry during the 12 months to July 2014 and will remain near the top of the league for the foreseeable future.
April saw the start of Network Rail’s CP5 programme, which is set to deliver £38bn of investment over the next five years.
The programme encompasses existing projects such as Thameslink and Crossrail, which together will deliver a 20 per cent increase in central London’s commuter rail capacity.
It also includes new projects to enhance the capacity and efficiency of the network.
Projects include the electrification of more than 850 miles of track, such as the Great Western Main Line from Maidenhead to Swansea, the Midland Main Line from Sheffield to Bedford and across the North and North-west of England.
The Northern Hub project meanwhile will improve the rail links between cities in the North, increasing capacity and cutting journey times.
The CP5 programme will also include the refurbishment, upgrading and redevelopment of hundreds of stations, including flagship projects at London Bridge, Manchester Victoria, Birmingham New Street and Glasgow Queen Street.
