Its only obvious that US model such GP40 are taller than European car. Instead replacing all my US loco's or replacing to US passenger cars I then tried to lower the loco's height. (just to make it look nicer).

Notice the blue line see the difference before and after the modification.

You should also notice the gap between the body and the wheels before and after I manage to lower the body shell.

Why of course all modification must have some plus and minus point. For example the coupler need to be replace.
