Wow, - you are correct in thinking I did not see the date. I wonder what brought that link up - I was not searching or going through stuff that old stuff. Anyway, the Mikado is a great loco.
One thin i plan to try, soon, is to change the body on them. It looks to be fairly easy to slip, say, the body of a GP 7 off and put on another diesel, or the Mikado and put on something else and change the trucks to make it something else. Brings up all manner of possibilities.
