Just dawned on me .... I have a Legacy Scale Polar Express Berk on order. Lionel states: "0-54 minimum curves."
Have you guys run your Berks on 0-48 Fastrack? Did it run flawlessly?
This engine, along with some PE cars, represents a large and unprecedented train purchase for my wife and I. Our Christmas layout is comprised of 0-48 curves and switches.
Thanks
Jim
