I bought a Lionel HO Challenger a while back. While we could argue some issues like the weight in the tender, proto paint and details, I am happy enough with it in all respects except one:
The driver/axle assembly is misaligned badly enough that at low speeds, the boiler moves from side to side, and at medium to high speeds, it shakes rather noticably.
If you have one or more, do they do this?
I sent the thing back and it took 8 weeks for me to get a "repaired" unit (total new mechanism) with the same problem. So I am wondering if most or all of these have this objectionable characteristic.
