A distant signal repeater of the Ks system seen in Sindorf on 11 October 2002. It shows Ks1 (expect proceed) together with a Zs3v with a "4" (expect speed limit of 40 km/h). The white light indicating the repeater function, which is off at Ks1 without Zs3v, is on in this case. What is not visible in the picture is that the green light is blinking. This aspect is only shown here when a train enters the local siding (Ausweichanschlußstelle).
