Cordel is deploying on-board infrastructure monitoring systems on UK railways using lidar, video capture and artificial intelligence technologies. Railway Supply magazine writes about this with reference to zdmira.


On October 28, 2022, the Reading-Basingstoke line, operated by Great Western Railway, was serviced by an equipped 165 series diesel train owned by the leasing company Angel Trains. This is the first time that Cordel’s on-board infrastructure monitoring tools have been installed on passenger rolling stock in the UK.

By analyzing data from lidars and video images using machine learning tools and superimposing them on the reference points of the Network Rail operator’s infrastructure, the system creates a digital twin of the line that displays the current state of objects, including the clearance of buildings (especially on bridges, in tunnels and near platforms), profile ballast prism, height, zigzag and extension of the contact wire, etc.

Widespread implementation of the system will allow the Network Rail infrastructure operator to reduce the need for specialized diagnostic rolling stock and move from routine maintenance to condition-based maintenance.

The deployment of Cordel technology is part of a five-year contract with Angel Trains. Cordel will equip its fleet of passenger trains with automated data entry equipment for the smart infrastructure system implemented by Network Rail as part of its digital transformation program.

Similar systems are also being implemented by Cordel on railways in Australia, Japan and the United States.
