Abstract

A method and an apparatus for operation of a railway branch line, which has line devices, in particular points, signals, axle counters, beacons and/or approach signaling devices, for specific functions. At least one first line device can be operated in an active mode and in a power-saving mode. In order to simplify the switching from the power-saving mode to the active mode, the active mode of the first line device is activated by a second line device when a rail vehicle moves over the second line device, possibly after a predetermined delay time has elapsed.
