I dug an old MARX 490 & slope back tender out of the junque box, Lubed it up, put it on the big Fastrack oval under the tree, hung a handful of old and abused 8-wheel plastic delux cars on the drawbar, threw up the throttle on my son's CW-80, and watched an Old School train chase its tail for a good, long (and noisy) time. Brought back memories.
The heck of it is, if I want to run my TMCC and Legacy trains on the big layout with the Cab 1, I will need to clean all the track, fiddle with the remote, fight with the rollers, and otherwise waste train time. That process brings back memories, too: why I got out of HO.
I know I sound like a single chime whistle, here, but that cheap, battered, low-end MARX set runs, which, at the moment, none of my expensive, pampered, newer trains do. There is a lesson in there somewhere. . . .
