I have notice now, on TSW3, the original mode for the PS4 Controller is not available anymore! As only option is the "immersive" one. This mode, is more "modern", but unfortunately you can not go so far away from the train on the sides, for viewing it! The view is really bad, just few meters away. So when you would like to take a picture of it, from the side is very limited. When the "old" mode - the original one from TSW2 - at least you have the "Free" one, you can move more far away of it, at the sides. Furthermore you can even see other details of the routes, which you are not able do it without it. Why it is too limited the side distance view on PS4? I am not requesting unlimited one, but at least we can go more meters away, to have better views from the side.
You can access the other cameras in Immersive mode by pressing left (internal) and right (external) on the D-pad when holding the camera change button. You can also choose which of the cameras is the default when switching to external view in the settings. It's not always easy to tell which camera you're in, so it's not a brilliant user experience, but what in TSW is?!
