I just left two trainloads of them parked overnight. In the 21:25 “Movement in Reading Traincare Depot,” (subtitled “Drive an Empty Stock Move within Reading Traincare Depot”), I found after parking and leaving the train, that it was full of passengers. Thinking it was something I had overlooked, I tried Service 5R79, this time opening the doors before I started to see if the passengers would escape. They didn’t – they were still on the train when I parked it. And there's not even a bar on these trains! This seems like a simple fix for the devs – there must be a way to toggle passengers on and off. Submitted as support ticket CJQ-336-45489.
