This is a note from Peninsular Corridor… “Fixed an issue with the first-person camera on the Route Introduction to allow it to be completed.” The exact same condition occurs in CN Oakville Hamilton Yard intro. Everything goes fine until you are supposed to explore the external views and then when it wants you to come back to first person you can but it doesn’t register it and you’re then stuck in the game having to exit.
I had the same problem today on the Main-Spessart Bahn, it worked for me after I switched back and forth between different camera positions like a madman.
I tried that also, but "no go". It just won't recognize the switch. I think it is a glitch from the carry over from the old multiple 8 camera view system to the new one in TSW3 that only has 2 options - in cab, or out. I kind of miss that actually. Especially the dedicated front & rear (I used them a lot in switching operations), and the wide boom.
