What is your experience with TSW4, when you use the Return to free roam option and then take the next service offered? I drive the most, practically so far, Bernina Lin I have to say that if I continue via Return to free roam, for example after arriving in Tirano and then I want to make a Rounaround and continue back to Ospizio, then the station announcement does not work, if I do not turn off the main circuit breaker and do not turn on the switch, then the destination station is not shown on the left blue display, sometimes there is also a problem with leaving the seat at the end of the service at the Ospizio, etc. It's nothing you can't live with, get used to, but......
The HUD still displays the last instruction of your previous service, that's a bit annoying. It used to disappear in earlier game versions, only leaving the compass on. (That's on PC, just saw the thread is tagged as "PlayStation". Nevermind.)
Bernina Line: And actually one more thing, I don't know if it's just a coincidence or if it's also related, sometimes the cars connect to the Allegra unit closely and sometimes with a strange distance......
I use it extensively on the Bakerloo Line. I like changing ends at the north end of the line, and then switching trains at the south end - just like in real life! I used to use it on the Rush Hour routes when I wanted to head back from London Victoria, Dresden Hbf, or Boston South station.
Nothing gamebreaking. It was mentioned above that the objective remains until you sit in another service, but I can look past that. I haven't found any other issues. Often it is more fun, because you get to set up your train like a real driver!
