Thanks, Jim - I chose Atlas trucks because of the better detail and scale accuracy. I agree with you completely about the IM trucks (Bettendorf, I think) that I like very much. I upgrade these with their metal wheels. Most rolling stock of the time had these trucks equipped so they will be all used elsewhere.
I got my first Protocraft trucks not long ago and they are fantastic. They roll like a sledge down the hill. To equip a large number of cars with these is too expensive, however. I use such high quality on signature items.
As it comes to rough track I must admit that I will do my best to avoid any. Measure my success or failure in the years to come :-)
