We work with our customers to develop and optimise the strategic infrastructure that will enable economic growth at both the local and national level.

As our population increases, the UK is demanding more from its rail infrastructure than ever before. It is estimated that we make 2.5 billion rail journeys every year, which is set to rise to over 3 billion by 2020. The current network is beyond capacity. Increasing demand will see growth in electrification, high-speed rail and the introduction of digital railway, making for a better connected nation.

What this might mean?

  • Large improvement programmes with whole-life cost and collaboration at the core of delivery values
  • Implementation of high-speed rail, ensuring this huge national investment is successfully delivered
  • The development of digital railway and an increasing focus on innovation to maximise the application of emerging technology across the network.
