I stopped in my local hardware store that still has a real nice hobby train section and spoke with the owner about building track. He said that rails, cleats, ties and ballast are available and he answered another question I had, in that HO scale is actually 1/87 scale. I tried matching up the Hobby Boss track and theres quite a bit of difference, but building our own shouldn't be to bad. I'm really starting to like these rail kits.
