PKP Polskie Linie Kolejowe S.A. has introduced a modern system for detecting faults in pantographs, devices located on the roof of electric locomotives used to draw electricity from the overhead line. Annually, more than 100 overhead line failures are caused by the poor technical condition of the current collectors. A damaged overhead catenary can cause difficulties for train travellers.
"Checking the technical condition of pantographs in real-time will not only increase the reliability of the railroad infrastructure but, above all, will reduce the number of network faults caused by the improper condition. Such a solution will significantly improve train traffic and reduce maintenance costs and the number of overhead line faults caused by the bad condition of pantographs," says Piotr Majerczak, member of the Board of PKP Polskie Linii Kolejowe S.A.
The system has already been tested on the Warsaw – Katowice line (No. 1) and the suburban Warsaw – Grodzisk Mazowiecki line (447). More devices are planned for deployment on the most heavily trafficked sections of railroad lines, where it will be possible to install the system.

Placed next to the track, a set of sensors, the DSAP (Detection of Pantograph Failure States) system, will diagnose the condition of the pantograph when the train passes. Measuring devices with the software will create a three-dimensional model of the pantograph and automatically locate any deviation from the reference condition. In the event of an incorrect pantograph condition, appropriate actions will be implemented, such as changing the faulty pantograph or stopping the train, thus reducing the number of overhead line faults. Reports from the monitoring of the equipment will be sent to traffic management centres and carriers, and with this information, it will be possible to take action to prevent overhead line damage from faulty pantographs.
The system was built by Zakład Robót Komunikacyjnych – DOM in Poznań Sp. z o.o. The value of the work is nearly PLN 6.7 million.
