Thanks to everyone for your comments and great input. The new factor that none at BMHR club had consider/discussed is "flanges per inch" on the forward cars...it makes sense...will try to incorporate in our future efforts.
To provide a timing context, we ran the nearly successful but stringlining train on 4/3/12.
We then spent some time pondering improvements/fixes, the major one being to put the heavier cars forward and the lighter cars rearward. Then on 4/26/12, we assembled and ran the successful 100 car train shown elsewhere on OGR foum at:

After this was posted, the Detroit Club posted a video of a 102 car train pulled by 2 locos on a flat layout with no serpentine curves, but heavy cars. So we are now gearing up for 120 to 140 cars.
More fun to come.
