A reader has submitted this question:

“I am having trouble in getting the passenger cars of a Harry Potter train set to go around a tight corner. How to I do this, so the cars will not hit the side of the mountain or de-rail? My layout is 30″ wide by 8′ long and the turns a very tight. Hope this is ok. It was hard to put this down in only one question.Thanks, Pamela”

Pamela, there is a section on “clearances”in the Model Train Help ebook. You will find this helpful in solving the problem.
