Intelligent Infrastructure (II) is a five-year transformation programme (2019-2024) focused on turning data into intelligent information to improve services for passengers.

It does this by giving maintenance teams the insight they need to proactively fix faults before they cause delays.

How will the Intelligent Infrastructure programme achieve this?

Working with the regions and our industry partners II will use existing and emerging digital technology to monitor the network and collect, collate and analyse data on asset performance. This information will be presented in an easy to understand format to provide maintenance teams with the insight they need to plan work proactively.

By analysing this data, teams can predict when, where and why faults are likely to happen. This warning could be 28 days, 90 days or even a year before a repair is needed.

This insight gives maintenance teams time to plan their work when it is least disruptive; it gives them the ability to group tasks to make the best use of their time and resources on site, and gives them visibility of degradation rates and access to maintenance history for railway assets.

It means we will become better at fixing the network before it breaks by using data to predict failures and be proactive instead of reacting after things have gone wrong.

What are the benefits of the Intelligent Infrastructure programme for passengers?

The II Programme presents a ‘big picture’ view of how everything within the network is related and allows us to be better at stopping faults that can cause delays.

Informed decision making

Teams can see what areas on the railway need attention to prioritise work – which means fewer delays on the network.

Turning data into intelligent insight for maintenance teams means they can make safer more informed decisions.

With improved visibility of what, where and when assets need repairing, teams can reschedule maintenance work and reduce the number of potentially dangerous failures.

Proactively fixing more faults before they happen and avoiding maintenance during peak times. If faults don’t materialise, they don’t delay trains, and services are more reliable all round.

What tools are II delivering?

  • Insight – a web-based decision support tool translating data into intelligence across the entire network in one place for the first time
  • High-definition aerial imagery and 3D LiDAR mapping of the entire network
  • New remote asset condition monitoring including at level crossings, embankments and overhead lines
  • New standards and processes to ensure data quality and consistency

These new tools and capability will allow colleagues to carry out ‘predict and prevent' maintenance and introduce more effective workload planning.
