Maybe there's a possibility to add a train that can go across a path, so that the gates close and the people have to wait as the train crosses over the path. This could be a great new transport ride or it could be an added feature.
This is something so many of us would love but I have no idea how difficult it would be to implement. I know in the workshop people have made the crossing gates but it can't sadly be properly functional.
Only way I can think this would work would be to have barriers sunken in the path that are triggerable, so that the crossing can be walked across normally but the barriers trigger on when the train hits the trigger point and stay on until the train clears the crossing. You can already make working crossings by building track through path. And there are crossing signals on the workshop. But, the peeps won’t stop and wait for the train.
