Mobile rail milling and monitoring at Metro Barcelona

28 March 2022 | 

voestalpine Railway Systems and PJM Measuring installed sensors on an existing vehicle of Metro Barcelona, hence the rail measuring was performed automatically.

The use of smart measurement technology and the integrated approach to determine rail condition in combination with maintenance measures, enables the operator to significantly increase efficiency in the operation of the infrastructure. Simultaneously, the risk of unplanned maintenance work at short notice is drastically reduced

Within a short time, numerous parameters were determined continuously on all metro lines, such as e.g. the quality of the transverse and longitudinal rail profile, the track gauge, and the vertical rail wear. The generated data was digitized and visualized in the form of a network condition report.

With our milling service, operational rail damage in track and turnouts can sustainably be restored. In order to plan this maintenance measure efficiently, it is very important to have the best possible knowledge of the rail condition in advance. With our combined services, including rail measurement technology, we offer an all-round carefree package for our customers.
