I recently had an upgrade done to my Cab Forward and now when I hook up the tender harness to the drawbar, the plug on the harness rubs tightly to the tender. The engine will not take any curve without derailing. Is the head on the plug larger, or did something happen and I got a shorter drawbar put on? The engine is a 20-3025 and I did not have a problem previously. I also had my N&W J upgraded and it's drawbar is about 3" long with two holes for selecting your distance. The cab forward's drawbar is about 2-1/4".
