I

roll on inclines of less than .2%. Fiddle with these as needed. If

your

cars are too free-wheeling they will have trouble coupling. This is
rarely an issue.

Really free rolling trucks will be sure to find any less than perfectly
level track.

I experienced the coupling difficulty back when I used a transistor
throttle.
