BEHAVIOUR OF PANTOGRAPHS AND OVERHEAD EQUIPMENT AT SPEEDS HIGHER THAN 160 KM/H. TEST RUNS ON THE FS WITH MORE THAN ONE PANTOGRAPH

The general and extensive investigations carried out by ORE Specialist Committee A 3 in the field of pantographs and overhead contact systems have been continued by Specialist Committee A 84. The investigations of this Committee are more limited, however, and have been focussed exclusively on the case of electric traction at speeds exceeding 160 km/h. The present report describes the results obtained during high-speed test runs carried out on a line of the FS network. The runs were conducted with one pantograph raised or with two pantographs raised, and with different pantograph spacings. The overhead contact system of the test line was composed of sections comprising a total of nine overhead contact system variants, each with different constructional characteristics. The pantograph and contact wire movements were measured and also the contact quality (contact losses). The influences of passing trains travelling at high speed was also examined. The results show that, in the case of the FS, no difficulty is anticipated for traction up to speeds of 200 km/h, when using a suitably-improved conventional type of overhead contact system or even when using two raised pantographs of the most modern FS type with appropriate pantograph spacing.
