Passenger cars can be equipped with truck mounted couplers using the correct
conversion bolster attachment. Truck mounted couplers permit closer coupling on
radii down to 18" without causing binding for most passenger cars. Non-Magnetic
trucks should be used with KadeeMagne-MaticCouplers. Wheels should be
changed on AHM and Athearn trucks. Use Kadee #521 or #522 non-magnetic wheels.
