Need to get the hang of setting the front view for the 321. I'm a bit picky and like to drive with no aid's like F5, so as I can see the brake gauge and speedometer clearly on the 321, I like to have the camera down. I tried setting numpad 5 to this slightly altered view, but when I move to the right with the right arrow key to set the destination blind, and move back to the left, it reset's to the original straight on view. I think I might have not done it correctly. I will try it again later on but the main thing is looking left and right is so much easier, it's extremely handy when coming into a station as I like to look left/right (depending on platform side) for the car stop markers.
Doing this with the mouse was difficult as you're trying to move the camera and concentrating on stopping too. Pressing numpad 4 or 6 makes it ten times easier!
Besides, I kind of strain my neck preatty easily, and keeping my head "TrackIR straight" puts some extra tension in that area, so CVK works out as a nice compromise for me!
