It seems very funny but in fact, it’s a dead end. 
That’s all folks ! Sorry to bother you with my very crazy idea.
Unfortunately for all of you, I don’t give up ! I have a new idea and I’m working very hard on it.
So I decided to build a new critter (better than the previous one, I hope) and hired a real professional driver. 
I would offer up a suggestion to look for HO gauge track made specific for On30 with larger ties and wider spacing which would look right at home on 7/8.
