I noticed that the control boards on my signals have optional connections labeled RIN and YIN (to force a red or yellow signal respectively). If I connect track common to these ports, the signal goes to the expected red or yellow values, which means I could wire these to the tortoise switch motors auxiliary relay throw... that could force a clear signal to red if the route the target is not selected by the switch. For example, the train is traveling a mainline is the switch ahead is set to a siding. Should the target for the mainline be forced to red (and the target for the siding be the appropriate value according to occupancy), or should the target for the mainline be based purely on occupancy and optionally, a ground dwarf added to indicate the throw of the switch??
Any opinions / experiences appreciated!!
