Remote online condition monitoring

Comboios de Portugal – Remote online condition monitoring

Regional Railcars, PT

CP and EMEF completed a refurbishment project between 2000-2004. EMEF equipped this fleet with a Remote Online Condition Monitoring (ROCM).

This project gave Portugal its first railway ROCM system, in order to promote operational and maintenance costs reduction.


  • No defect found faults average decrease of 27.5%
  • Reliability average increase of 12.5%
  • Availability average increase of 9.5%

The installed system collects the required data from the existing on-board equipment. The data is then sent to the on-shore central system for data analysis, acting as a decision support tool for the operations and management teams.

Intelligent Fleet Management is delivered by Nomad Tech.  Nomad Tech was created as a joint venture with EMEF, the Portuguese Railways company for rolling stock maintenance. For more information please visit Nomad Tech.
