While driving a train, you can use camera 3 to move your view a bit above the train. Which is nice, because you have a much better view of the landscape. In first person mode, you cannot do this. It would be nice to have something like a helicopter view, that allows you to fly over the tracks, land if you like to pick up a collectable and so on. During route creation a lot is done you hardly ever will see and that is a waste. Heicopter view may reduce this waste.
