PJM tested pantographs on ÖBB KISSes

Stadler Rail relies on the expertise of PJM to test the pantographs and wheelset torsional oscillations of the KISS double-decker EMUs: until the end of January 2025, PJM carried out dynamic track tests in the pantograph area as an ISO/IEC 17025 accredited test center. The vehicle tests in accordance with EN 50317 took place on the Westbahn between Wien and Salzburg, and on the Franz-Josefsbahn.

The measurements were carried out in multiple traction of three KISSes - two four-car Class 4734 units and one six-car Class 4736 unit. Hence, the vehicle data and data from two measuring pantographs were recorded synchronously. PJM is the only company in Austria that is accredited for pantograph testing.

The train continues with further test runs. E.g. in February, the vehicle was tested for wheelset torsional oscillations, with eight telemetry systems used to determine and record the strains on the wheelsets.
