By the way, you can see in the high-res picture that the battery box in the
two train sets is not the same as rechargeable battery box (item 8878)
as previously thought.
Presumably then, this battery box is rechargeable only if you put rechargeable
batteries in it.
In any case, both train sets look awesome, I can't wait to get them. I'll probably
run them with a 9V motor on 9V track, sell the RC track, and then use the remote
control power functions to power various things sitting next to the track, though I
haven't decided yet what that would be (perhaps I'll build a remote controlled
crane, and a remote controlled switch point).
