pantograph which slide along the contact wire facilitate the transmission of power The pantograph and the overhead contact line system form two oscillating sub-systems which can be displaced There exists a unilateral sliding linkage between them, which shall ensure continuous contact Their design shall allow for minimum wear of both sub-systems when used BS EN 50206-1:2010 EN 50206-1:2010 –6–
