Thank you, shorling. I will give this a try when I get a moment. I agree that it appears the corners (points?) are what kick the taxi off. I found with a little more experimentation that there seems to be an "exact proper speed" where it is much more reliable, although not 100%. But, I really don't want to have to be that precise every time. It's just one little add to my overall locomotive based layout and I don't want to have to fuss with this little taxi when people are over watching trains run.
