Introduction
This document corresponds to the aim of the EN 50206 series.
The electrical power of a transmission unit is achieved by collecting current from a conductor rail by means of
one or more current collector(s), which is/are installed on the traction unit or on a vehicle of the trainset.
The collector shoes of the current collector which slide along the conductor rail facilitate the transmission of
electric power.
The current collector and the conductor rail form two oscillating sub-systems which can be displaced. There is
a unilateral sliding linkage between them, which ensures continuous contact. Their design should allow for
minimum wear of both sub-systems when in operation.
