New sensor systems will allow GTR to detect when train components need replacing
New wireless sensor systems to monitor when maintenance is needed will be installed on four additional Govia Thameslink class 170 units joining the existing class 171 fleet.
The sensor systems, from Perpetuum, collect vibration data and transmit it to a database, where software algorithms look for signs of wear on bearings and wheels.
The systems, which were installed in 2014 on a number of Southern trains, which are now part of Govia Thameslink, allow TOCs to save money and improve safety by identifying and replacing components when they develop problems, instead of removing components on a mileage basis whether or not they’re still working.
Govia is also building a £200m fleet of class 700 variants on the Great Northern route. Govia have also been shortlisted for the West Midlands franchise.
