I have a Lionel 6-28415 Bumper Trolley. It looks good, but it is a terrible runner because of its slider shoe. My goal is to save this Brill from the scrap yard display by somehow grafting its body to an MTH bump-n-go trolley. By far, the MTH bump-n-go trolley mechanism is superior. However, if somebody comes up with a practical roller pickup installation for the Lionel car, then I will try it on this 6-28415 Brill.
