Network Rail’s Digital Railway Strategy to keep UK on track

10 May 2018

Transport Secretary Chris Grayling launched Network Rail’s Digital Railway Strategy, a commitment to ensure trains and signalling are digital or digital ready from 2019.

Mark Carne, chief executive, said: "Not since the railway transformed from steam to diesel in the 1960s has a technological breakthrough held such promise to vastly improve our railway for the benefit of the millions of people and businesses who rely on it every day.

“The age of a digital railway has today moved from the drawing board and into reality as we reveal a blueprint that will improve the lives of millions of passengers and freight users across the country. Today’s commitment is to adopt and roll-out new digital technology, for both trains and track, which will deliver faster, more frequent services for passengers and businesses alike, giving our economy a massive boost."

Services through London Bridge, into London King's Cross, Waterloo, and across the Pennines, are to be the first to reap the benefits of this technological leap as the blueprint earmarks these routes for transformation over the next five years. 

Mr Carne continued: "We, Government, and the wider rail industry, have been working tirelessly behind the scenes to get the concept of a digital railway off the ground. It is now a reality.

“In a world first, digital train control with 'fly-by-wire' trains (automatic train operation) – coupled with smart infrastructure, is now a reality on Thameslink services through London Bridge. We now have a plan, impetus and the funding, to introduce these systems across large swathes of our railway network over the coming years.

"This is a turning point in the history of our railways as we move firmly into the digital age.”

Over the past two decades passenger numbers have doubled and continue to grow but our railway, laid out in Victorian times, is full to bursting, especially at peak times on our main rail arteries into urban centres. Big capacity boosting infrastructure projects, such as Thameslink and Crossrail, are expensive and cause years of disruption while digital railway offers an alternative way to deliver additional capacity, making the most of what we already have.

Over half of Britain's analogue signalling systems – some still based on Victorian technology – with lineside traffic lights controlling trains, will need to be replaced within the next 15 years. A like for like replacement would cost circa £20bn and deliver very little in terms of passenger benefits. New digital signalling offers a more cost-effective alternative that also brings significant benefits for rail users, such as more capacity, speed and reliability.

Digital train control is already a reality on the Thameslink core through London Bridge and on Crossrail.

In the five years to 2024 the industry is planning to introduce it across the Pennines, on the southern end of the East Coast main line into London King's Cross and onto some of the major commuter routes that feed London Waterloo.

Within 15 years, the aim is to see 70 percent of journeys benefit from digital railway technology. Launching the new 'Digital Railway' strategy at a special event in York, alongside the Secretary of State for Transport, Chris Grayling, Mr Carne concluded: "Transforming our railway into the digital age offers the chance to deliver huge benefits for our passengers and the freight that this country depends on. It is the most cost-efficient way to deliver the future railway Britain needs."

In response, Peter Selway, Rail Segment Leader at Schneider Electric commented:

“The announcement by Chris Grayling committing to digitising Britain’s rail network is significant not just for passenger convenience, but also in terms of to the UK’s economic performance.  The late running of trains costs the economy around £1billion a year. We have seen vast improvements in similar projects in cities such as Tokyo, Sydney, Beijing and across Spain and France. Some of the greatest benefits of rail digitisation come from real-time data and smart analytics allowing for predictive maintenance. By anticipating outages and problems before they occur, we could be taking preventive action to avoid unnecessary cancellations, improve commuter experience, and cut costs. This is an exciting time for UK rail.”
