After leaving my service at Rochester (465) and its left under the control of the ai, I'm still hearing the dsd and aws sounds. An hour later after my old service should be long gone thru a portal and im driving another service (375) I'm still hearing random dsd and aws sounds.
Can I check if this was on the 'Temporary Contract Scenario'? We are aware of some issues with the aws playing and AI trains.
I’ve had this happen at times in the past on tsw2. But quite some time back so I can’t recall which route or loco. haven’t come across it lately.
This can be solved by turning off the safety systems before leaving the service. It’s a very common occurrence on London Commuter timetable too, at least it was in TSW2. When an AI train completely leaves the map and then returns to the map on another service later, the warnings will also return if the safety systems were left active, as is described in the OP.
