Oops...
Okay , in all fairness, I read the Lionel advertisement at my local hobby store, and it clearlystated only TWO powered trucks., so that should be a surprise to no one. If there IS a problem, then Lionel should fix it under warranty, because if it craps out just hauling its own tender, imagine what happens if you couple it up to a train
Espescially for what you're paying for them.
On the other hand, I just read the review on the Lionel Challenger in RMC, and they couldn't say enough good things about it. I suspect that this may just be a production glitch with the Turbines. Nobody should panic just yet,but keep it open as an option.....
