What radius are you running? The f40ph is short enough to handle almost any radius, but full length passenger cars will require a much bigger radius curve. If you are running 18 or 22 inch radius curves, you will probably need to stick to Athearn "shorty" passenger cars. If you have 26 inch or bigger minimum radius, then you can run the full length cars with some coupler mounting modifications. With a 30 inch or larger radius, you won't have any problems.
