Playing a nice drive at Sandpatch, I used external camera 2, when the train entered the tunnel between Hyndman and Mance. The camera kept hanging just before the tunnel entrance and I could not change it back to camera 1 till the whole train left the tunnel again. At other routes, I have seen the camera switches back to camera 1 inside a tunnel, like the normal behaviour of TS2020.That makes sense to me. I think what I see here is not like it is intended to work. It does not make sense, especially if you want to drive without HUD.
