Perpetuum: self-powered rail safety technology drives jobs growth

A fast-growing spin-out from Southampton University has used EU research funding and innovation funding through Innovate UK to further develop technology for the rail industry that is improving safety and reliability and delivering significant cost reductions.

This has established Perpetuum as a global market leader. More than 45% of the company’s sales were exported in 2015 and this is expected to rise to 70% or more over the next 3 years.

Volume orders and trials of its self-powered condition monitoring systems for rail operators around the world have resulted in staff numbers almost trebling in the last three years.

Perpetuum wins contract to supply Govia Thameslink Railways

Perpetuum, the global leader in vibration energy harvesting and its application in asset management across the rail industry, has announced that it has received an order from Govia Thameslink Railway to supply wireless sensor systems for four additional Class 170 units joining the existing Class 171 fleet.

The sensor systems monitor wear of the bearings and wheels to help maintenance engineers determine when maintenance is needed. Perpetuum’s world leading Energy Harvesters enable the self-powered maintenance free wireless sensors to be fitted in a few minutes without the need for complex retrofit wiring. This new agreement follows the successful installation of Perpetuum sensor systems on a number of Southern (now part of Govia Thameslink Railway) trains in 2014.

How wireless wheel monitors could identify railway track faults

Southeastern Railway has equipped its entire fleet with energy harvesting wireless sensors to predict wheel bearing failures. Now it wants to share the data generated by the technology with Network Rail to help it predict track faults.

Train wheel bearing failures used to be a big headache for Southeastern Railway’s engineering director Mark Johnson. The man who is responsible for the train operator’s entire rolling stock and some 550,000 passengers daily, used to dread a fault occurring while one of his trains was in service.

“Should it happen in the wrong place, a fault could wipe out the whole of the South East for 24 hours,”
