O-K,
I’ve been crusing the garden forum (Kalmbach), and came across the pooper scooper car at http://www.trains.com/community/forum/topic.asp?TOPIC_ID=40242.
FORT-U-NAT-LY, we don’t have to have one of these ummm, track cleaners,–that is, unless your cat takes to your kitty litter ballast.
Soooo, as you can see, there are some downsides to the larger outdoor trains that most of us perhaps envy. After all, bigger is better. More heft. Uggggh.
