Ed,
Welcome to the wacky world of S. Glad you ran into Francine's crew! I'm interested in all flavors of S, from classic Flyer to scale, but love the feel and look of the old toys. I like to resurrect old items and get them back on the track again. Also scratch build things, either as Gilbert "what ifs" or numbering rivets with the best of them. Weird, right? And Francine, DCC in a K5? Whoa, too hi-tech for me! (kidding). BTW, here's my resurrected K5 (was a junk box item for $15). Straight DC can motor, LED headlight and prototypical paint. It actually fooled one of the scale-only guys in our club... at least for a while.
And watching kids chasing a train around the layout is one of the greatest things about setting up at a show.
