Thanks guys for the quick and informant replys. so i guess it will be mostly changing locomotives over. some of my rolling stock is cheap new stuff that i don't mind modifying, i suppose i can make an adaptor car if i ever want to run my old stock around the track, or just use my old engine. Anyway it sounds like kaydee is the way to go. And did someone say that cars you assemble your self are a much more cost effective way to go? because grain cars up here sell for $25 and up and that seems awfull high even if you only drag 10 at a time. i have a 200? Walthers catalogue but i don't really know what to look for,, hey as long as its Canadian i'm interested. I started a layout in the basement at the farm, but now that were in town, i have way more room but my folks (mom) is bucking the idea of moving it here, but since the farm house is more of a summer home and unheated in the winter i don't want to put anymore work into it because the moisture and temp will just ruin it.
