I have a rail system set up like this.
A<->|<<---------<-|<----------<-|<->B
|-1>--------->|-2>------ 3>>|
-> = One way signal
<->= 2 way signal
| = crossing
A and B = stations
There is a problem i have where The train will wait at 2 until the other passes 3. Is there any way I can keep the trains moving?
Since the prupose of a signal is to keep the track protected, no, there is not. In Simutrans trains have predefined routes which do not change during the trip (just like real trains). YOu could set waypoints to force every second train on the other track, but that might get deadlocks depending on your overall design.
