Its an attractive engine Lee but keep an eye on the fasteners for the side rods and valve gear. If they get loose the eccentric may break and Lionel has no replacements. The eccentric is fairly fragile. This engine uses the same chassis as the original Legacy Santa Fe Atlantic from around 2007. The same chassis has been used for every Atlantic since. Why they can't can't stock that part I will never understand. I had to fabricate one for a friend just a few months ago.
