Monitoring areas in real-time further enhances safety, helping detect potential hazards like overhanging or invasive tree species, leaves on the track, or embankment subsidence that could cause harm or delays. Network Rail previously estimated that vegetation-related incidents cost up to £3 million annually in the Southern region alone.
The new forward-facing CCTV camera (FFCCTV) has been installed inside the driver’s cabin of a LNER Azuma train for the 12-month trial. The operational Azuma train now has a role in digitising infrastructure monitoring and maintenance on the East Coast Main Line. This solution uses artificial intelligence (AI) camera sensor technology.
Automating the detection of potential hazards, combined with pinpointing where maintenance is necessary, enables a proactive approach to infrastructure maintenance. Equally, the trial will provide insights and guidance to optimise when and where maintenance is needed on the East Coast Main Line.
Hitachi Rail is helping to convene the pilot project using its digital supplier CrossTech. The UK SME is one of Network Rail’s AI technology success stories, using computer vision technology to live monitor tracks and the surrounding environment via data that comes from the forward-facing video camera.
The FFCCTV monitoring solution was developed by combining CrossTech technology, with Hitachi Rail’s digital expertise to assist with integration, operations and customer interface. This is an example of a global rail business incubating and supporting British SME innovation.
FFCCTV is the latest development in a wider suite of Hitachi digital asset monitoring solutions which can live-monitor tracks, overhead lines and the train itself. These digital solutions, working either independently or in combination, allow for automated and more accurate monitoring to help modernise the railways.
Johanna Priestley, route engineer at Network Rail, said: “Vegetation is the only living asset on the railway network and as such understanding the potential risk to trains is ever changing. Using forward facing footage allows us to ‘see’ from the driver’s perspective. We can use this technology to understand where vegetation is encroaching on the operational railway and at risk of making contact with either trains or fixed infrastructure such as overhead electrified wires. We can also identify where vegetation growth has compromised the driver’s view such as on the approach to signals or level crossings. This initiative will allow us to make passengers’ journeys more reliable and help minimise the risk of disruption on the network.”
Nick Hughes, senior director, sales UK & Ireland at Hitachi Rail, said: “FFCCTV is the latest in a series of digital asset monitoring solutions that together have the potential to revolutionise real-time data collection and visualisation by trains running across the UK, generating valuable insights that drive better decisions.”
