Wow, between Gary and I, two tutorials in one day! :)
I remember a few months back there was much knashing of teeth about building an Athearn covered hopper. I said it wasn't that hard, so putting my money where my mouth is, you can now see exactly how I build one without any problems...
(Note, this is not linked off of any of my pages, so you can only find it from this newsgroup post ATM).
Cheers!
