Most, if not all, models are of Japanese oeverhead wire system. Simple box trains and cars with build up sleds on top, also a few buildings and such; nothing hard enough to require instructions. If you get stuck on a particular model a quick Google should provide more than enough info to answer any questions. Enough models here to keep you going for a long time!
It's still there and I downloaded it the other day. I'm pretty sure I've found it before long ago, but it may be on an old drive (you know how that goes). Nice link, Doug. I had to grab the 1880s American engine and coal car.
