I recently purchased a Lionel Legacy, Western Maryland Shay rated for track 0-31. It ran beautifully on my 0-31 tubular track without any rolling stock attached. As soon as I attached one car and it went into a curve it jump the track. There was binding between the two frames. I tried it with different cars. Same problem. The engine is rated correctly, but I'm sure most folks one like to hook up a few of the post-war log cars to make this one special consist. Unfortunately, I only have 0-31. My LHS, MB Kleins in Maryland graciously took it back and gave me full credit. They were unaware of this issue. Has any one else had this problem? I think Lionel should have posted this problem in the catalog or just not rated it at 0-31.
