I was hoping to build a really long underground tramline, but ran into some problems during wiring up of the call buttons. The main issue is the limited wire range which prevents me from directly connecting two tram stops (they are really far apart). So I decided solving the problem using XOR-gates which act as wire bridge elements. This did not work as the signal from my source tram stop did not arrive at the target tram stop. Is this intended? Can the tramstop network only consist of direct tramstop to tramstop connections? My current workaround is simply using more tramstops between them....but this requires pressing direction buttons at every intermediate stop which kinda defeats the purpose of the tram (i.e. travelling a long distance without button presses..) or else the tram...well..stops.
