Ive used it quite a lot and not come across any problems but not sure if the triggers can be used more than once as ive set up different trigger names for each area that uses this rule.
Ah, now I remember, the reason I didn't use the "multiple" in this case was that It will set the signals to "danger", and does not give me full control of when and where I want the signals to revert to automatic (trigger radius dependent), and some of my setups require the opposite setting.
No I didn't mean using the triggers again, but using the rule multiple times.
Does not seem to create any problem with a lot of "trigger checks", just asking because I haven't found use for the "multiple" as yet.
Danger would be correct as the triggers activate when the bridge opens (up). When bridge is closed (down) the signals are automatic. This applies to the bridges with ship track.
