On Peninsula Corridor there are a bunch of crossing signals stuck in operational mode (but with gates up) between Atherton and Palo Alto with no trains visible or on map in area to cause such a circumstance. Likely more elsewhere on route. I found them whilst walking the line for route tasks. Not sure if important in this case but I am on Xbox 1 S This one of them... Might be worth a look by the Dev team ... DTG Matt.
