Southeastern, Network Rail, and Cordel have partnered to install advanced LiDAR sensors on rail maintenance trains, marking a key step in the upgrade of Southeastern’s Metro fleet. This initiative aims to collect accurate data on platform dimensions, supporting the design of new or improved trains with a focus on accessibility.
Cordel has equipped two Network Rail maintenance units with Light Detection and Ranging (LiDAR) sensors, using artificial intelligence (AI) to create 3D models and accurate measurements of all Southeastern Metro station platforms. As platforms across the network have been modified over decades, their shape, height, and curvature vary significantly, making precise data essential for designing trains that maximize unassisted boarding.
The collected data will assist train manufacturers in designing trains that accommodate passengers with mobility challenges, as well as those with luggage or pushchairs. The goal is to improve accessibility and provide a more inclusive travel experience across the Southeastern Metro network.
The LiDAR sensors, installed on the maintenance trains, will continually gather data as the trains operate across the Southeastern network. The data will then be processed by Cordel and shared with Southeastern for further analysis.
Improving accessibility and efficiency
Mark Johnson, Engineering Director at Southeastern Railway, commented, “Our upgraded Metro fleet aims to improve performance, operating costs, and accessibility. The collaboration with Network Rail and Cordel is essential to providing highly accurate platform data, which will help ensure the new trains are optimized for the Southeastern network.”
The data gathered will include detailed information about platform height, curvature, and gaps from trains, providing manufacturers with the critical measurements needed to design the most suitable trains. Johnson added, “We look forward to receiving the first data in the coming weeks.”
Cordel’s AI-powered LiDAR technology
John Davis, CEO of Cordel Group, highlighted the role of Cordel’s modular LiDAR technology, saying, “Our sensors are now integrated into Network Rail’s maintenance units, capturing data directly from trains in service. This data is processed using our AI platform, delivering the precise measurements required by Southeastern and approved by Network Rail.”
Cordel’s AI-driven platform enables the rapid production of accurate 3D images and measurements, allowing for better alignment between trains and station platforms, ultimately improving the passenger experience.
A step towards a more accessible railway
Bob Coulson, Kent Route Infrastructure Director at Network Rail, emphasized the significance of the collaboration, stating, “This partnership is a critical step toward making the railway more accessible. The data we collect will provide manufacturers with the information they need to create a more reliable and sustainable railway, contributing to our vision of improved service across the Kent route.”
