Great Running Engine.. Love it.. However it has a Coupler issue.. it derails ( Pulls/ Yanks) any size car on any curve and any switch... It even derails a heavier engine...After multiple inspections and verifying everything is free and no restrictions , still an issue.. Something is restricting the ease of motion ( does not matter front or rear couplers behave same ) Has anyone experienced this issue on any Lionel SD38's. FIX..?? PLEASE...!!
