So there have been many many times when I'm driving a passenger train, open the doors to let on passengers and then get distracted by my phone or the TV or something and then I miss the notification to close doors and end up running a minute or two late. I can't imagine I'm the only one to do this especially when a station stop lasts for several minutes so I'd love to have an audio cue when it's time to close the doors such as a guards whistle or even the beep we get when we've completed a task.
