My 6yr old son was very happy to unwrap his Lionel Polar Express Berkshire engine with whistle steam. Unfortunately, the engine makes no chugging sounds right out of the box. I should have tested it the day it arrived so I blame myself. It is pathetic, but I have absolutely come to expect this kind of total lack of QC from Lionel. I will take it apart and see if there are any loose wires. If not, I'm sure that it will get fixed by Customer service. It sholdn't come to that though. Perhaps Lionel should open and test every engine once they arrive here in the US? I guess it is easier to just have good customer service and push the QC role to the customers. I have to say that of all the O gauge trains I've purchased over the years the vast majority of out of the box failures have been from Lionel.
You only get one shot at Christmas morning. Like I said, I blame myself for actually trusting that it would work.
