Perpetuum wins long-term RCM contract with Swedish rail giants SJ


Innovative Remote Conditioning Monitoring (RCM) specialist Perpetuum, has beaten off tough competition to win a 10 year contract with Swedish state-owned train operator SJ to monitor its fleet of high speed X2000’s.

With over 4,500 employees and serving 275 stations, SJ aims to one of the most digitalised companies in the world within the next five years. It has chosen Perpetuum’s cutting edge RCM technology and analytical solutions to move its wheelset maintenance away from distance-based to condition-based decisions. Perpetuum’s solution will give ‘inflight’ analysis of train fleets, track, bearings and wheels and ensure maintenance is correctly focused.

Perpetuum won the contract following tests conducted during an 18-month trial on 80 wheels in the harsh Scandinavian environment. Perpetuum will monitor the wheelsets by using its Bearing Health Index and Wheel Health Index solutions, the algorithms of which have been deployed around the world on over 8,000 wheels travelling over four billion km. Supporting the solution through a 10 year service agreement means Perpetuum can future-proof the data and information streams for SJ, even if there are upgrades to the on-train or back office ICT architectures.

“Perpetuum has proven to be a reliable RCM supplier who delivers cutting edge technology that will help us improve our operation and service to our customers even further,” explains Arvid Fredman, Fleet Manager X2 for SJ.  “The investment fits well with our strategy to be in the forefront of digitalization and continuously striving for efficient and cost effective maintenance.”

“The data collected by Perpetuum can be used to predict failures, increase asset management efficiencies and improve safety, meaning more time on the track for the bogie and a better chance of meeting increased demands over the next decade,” explains Justin Southcombe, Commerical Director for Perpetuum.

“SJ’s X2000 is the tenth fleet the Perpetuum Remote Condition Monitoring system has been deployed on and we are delighted to be working SJ, our first contract in the strategic Scandinavian market.”
