I think I'm missing something, what triggers the "draw bridge" to lift? and what affect does that have? does the rail become impassable? The boat can drive right through a lowered bridge.

The draw bridge shoudl open by itself, when an automated ship crosses the bridge. Manually driving a boat sadly wont trigger a lift. The rail does not become impassible, only "blocked" signal wise. In the end the bridges function mostly for having a visually pleasing rail-waterway crossing and for engine limitations dont have all the funbctionallity i would like them to have

Thanks, I thought I tested it with an automatic boat but I probably just tested it with a manual one. Curious how they work for auto and not manual, are they just rail signals that have an animation for when they get "reserved" (yellow)? Guess I can answer that by looking at the code. No sarcasm, fantastic mod.

thanks! there are a number of rail signals that are checked for state-changes, depending on those the bridges state is also changed

so can you force one of the signals to manually open the bridge?

nope. i had been thinking about also creating a bridge that only opens on player input or via the circuit network, but for now i dont have the time and there are other features that i would like to implement first.
