Hmm, the save game feature in TSW5 is remarkably and comically underbaked. In freeroam and want to keep the train you're on for the whole service and do it one run a sitting? I mean, it's a virtual train you're driving for fun, not a paid job, after all, so a perfectly reasonable ask.
Nope, fuck your timetable, not saved.
Now that I'm not dying coughing this hit me as weird.
