First pantograph inspection installation in Poland

PKP PLK commissions first pantograph inspection unit in Poland

First pantograph inspection installation in Poland PKP Polskie Linie Kolejowe S.A.

Polish rail infrastructure manager PKP Polskie Linie Kolejowe has taken its first pantograph inspection installation into use. By detecting faults in pantographs, the more than 100 annual failures in the overhead line network as a result of poor technical condition should be reduced. 

The pantograph inspection covers the line Warsaw-Katowice and the Warsaw-Grodzisk Mazowiecki suburban line. Further installations are planned for the most heavily trafficked sections of the railway line. “Real-time control of the technical condition of pantographs will not only increase the reliability of the railway infrastructure, but above all reduce the number of network faults caused by their improper condition”, Piotr Majerczak, member of the Management Board of PKP Polskie Linii Kolejowe, commented. “Such a solution will significantly improve train operations and reduce maintenance costs and the number of overhead line faults caused by bad condition of pantographs.”

The system diagnoses the condition of the pantograph whenever a a train passes under it. The measuring equipment and software create a three-dimensional model of the pantograph and can automatically locate any deviation from the reference condition. Monitoring reports from the equipment will be sent to the traffic control centres and the operators, and with this information, action can be taken to prevent damage to the overhead contact line by faulty pantograph, such as changing a faulty pantograph or stopping the train, says PKP PLK. This should reduce the number of overhead contact line faults, and consequently the number of train delays.

The system was developed by Zakład Robót Komunikacyjnych, a subsidiary of PKP PLK. The value of the works is around 1.4 million euros (6.7 million Polish złoty).
