Abstract:
A track test load device includes an inductor assembly with simulated track inductors simulating a rail track, a connector assembly for connecting the inductor assembly to a constant warning time device, and a multi-way-switch-assembly with a multi-way-switch with multiple switch positions. The multi-way-switch assembly is operably coupled between the inductor assembly and the connector assembly, wherein a switch position of the multi-way-switch corresponds to an operating mode of the track test load device. Furthermore, a track test load system and a method for testing a constant warning time device are disclosed.
