Back in 1958, it was me.
Fifty-seven years later, this is the #1 grandchild's first exposure to an O gauge Christmas train.
That's the very same Marx #666 in all these photos. Below, it is mated to a Lionel 234W whistling tender, a couple of Lionel Christmas cars, and an RMT Christmas caboose.
He loves playing with my old train set, blowing the whistle and watching it run.
I think we've got a live one!
