I have an MTH trolley that I am running on Super Streets using the D21 curves. I have one curve that the trolley gets stuck in (wheels spin) despite my efforts to remedy the situation. Interestingly, if I turn the trolley around (drive wheels now in back rather than in front), the trolley runs through the problem curve with no issues. Moreover, I can run it at a lower speed through all other curves which I prefer. The issue is this, by turning the trolley around, it always wants to start in the "backwards" direction. I can start it, change direction, and then it is fine. However, I want to set it up for automatic station stops w. announcements and don't know if I can do that when the engine "thinks" it is running backwards. Is there a way to change the normal direction on this trolley which would eliminate this problem?
Thanks, Paul
