Rail & Road Infrastructure Monitoring


Our engineering team has over two decades experience in the design and delivery of system to monitor railway infrastructure. Back in early 2000 they were the pioneers behind the UK’s rail industry rail temperature monitoring system the RTM that went live in 2003 and wone a prestigious Railway Innovation Award. They also developed an on train, real-time, hot axle box monitoring system, took part in various studies to investigate non-evasive methods of detecting faults on OHL systems, and delivered a VHF FFSK radio based system to decode tokens from RETB to control level crossings.

More recently they have become joint patent holders on a simplified railway infrastructure design and have working with the Network Rail Innovation team successfully demonstrated the viability of using the Iridium Satellite network for critical railway monitoring applications in areas devoid of cellular coverage and power.


We have been part of various teams looking into Smart Highways – from gully monitoring, drainage to automated ice warnings.

We also supply automated flood warning signs that are can trigger a whole variety of signs to warn drivers about flooded roads or high levels on fords.
