Regarding your problem with the coaches on the smaller radius of the curve - Check that your bogies have enough swing - I have some 57 foot Boxcars that weren't happy doing that, and discovered that the bogies swing was being limited by the coupler boxes - the back of the wheel was catching the back edge corner of the coupler box - a small trimming job on the back corners of the coupler box has cured the problem. Regarding the tender - check your back to backs, but also check that the curve radius isn't too tight for the fixed wheeelbase of the tender, which will prevent it from taking the curve properly. A possible cure might be to remove the flanges on the centre set of wheels - if there is no other way of solving it - I know that some fixed wheelbase 0-6-0 and 0-8-0 locos also have this problem and will only work happily on larger radius curves
