I saw a great article in an old TTOS Bulletin on Scratchbuilding Standard Gauge. I'll scan it in and get it posted!
Check out the pic! Wow, very nice!

Anything that will remotely fit into the category of Standard Gauge Trains and Toys!
Thanks for the compliment on the mining cars. They're heavily kit-bashed "G
scale" logging cars from Ozark miniatures: I'm working on several more. Whole
thing started when I went looking for Voltamp couplers, and came up with link
and pin logging couplers that hook up to the Voltamp steeplecab by Pride Lines
quite well. There's a bit of work to enlarge the wheel sets from 2 inch to
2 1/4 for Standard Gauge, but nothing patience and a small file can't
accomplish.
