Narlie, based on the 3800cf cylindrical hopper, I think these will both roll well and couple and remain coupled. I will not miss the lighting features, and appreciate not paying for feature I'll disable... the original run by Rapido had some bright, bright interiors!
I had problems with my 3800 hoppers, had to sink bolster screws to stop rubbing on the axels.
For the first run International PSC van I replaced with MT and said goodby to lights. My other 2 units function with so so free rolling.
Let us hope the new release will be good. Have ordered 4.
