i save a game turn of my PS4 and come later and press last played it puts me on the train but the objective marker will diserpear or if I was loading passengers it would stop and then I have to restart the game and sometimes it press last played and puts me in a seat with a person already in it
Which route were you on? I have had this happen. But I have since noticed that it doesn't happen on the 3 base routes, that is those originally included on TSW (GWR, RT & NEC). It looks like it is only the DLC's that tend to throw a hissyfit if you quit during a service, especially while loading passengers.
