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.

The class 442's have these fitted to measure vibration on the axleboxes, and suspension tubes. The idea is that the sensors pick up vibration in a bearing that is degrading before it starts to generate excessive heat.

With Abellio Scotrail releasing some of their Class 170's to be cascaded to Southern Trains (GTR) to be reclassified as Class 171's and to work alongside the current Class 171's for the London Bridge-Uckfield/Oxted and Brighton-Ashford via Hastings routes.

So does it work on ticket office staff? :)
