I recently purchased a new undec bachmann 2-6-6-2 engine with factory DCC. I have found that the tender coupler rides too high due to some sort of spring action within the rear truck, and decouples from cars frequently. The loco also has great difficulty pulling just 5 passenger cars up a 1.5% grade.
Does anyone have a suggestion for correcting these two problems?
