+1 on reaching out to Garhauer. I put an ezcar system on my genoa track and I love it! Garhauer service is terrific. I ordered the wrong kind of car for my existing track, I called them with the issue, the guy said you ordered the wrong kind of car, I'll send you the right one overnight and send the wrong ones back when you can. No credit card.... no deposit. It arrived next day and the proper car went on smooth and easy. I like me some Garhauer!
