It would be a nice feature to be able to play as a conductor on a passenger train to scan people’s tickets and open the doors at stations for them. Vote!
Onboard announcements, automated or recorded would be awesome as well. Also the ability to give the engineer the “all clear” buzzer when all the doors are shut. All in all this would be an awesome feature!
That's part of the Passenger Information System, which has been in development for a while now. It's supposed to handle onboard announcements, station announcements as well as all the dot matrix schedules boards at stations and on applicable trains.
I would love that. I hope they do that I play it on ps4 and would love to be able to be the conductor of a service
