Gene,
The 3 day show was the Antique Power Assc's annual show featuring Oliver tractors in Rainsville. The 7.5 inch gauge track is the Pine Creek and Western club which has about a half mile of track around the show grounds. The loco belongs to my wife and I. We had it built by Morris
Railway Supply. It took about 8 months to build. It has a 5 hp gas engine and hydrostatic trans. The paint and lettering were done in Laf. It is very close to an SW9. I wanted a Monon loco and chose the open switcher number. The rider car will get a roof and ladders and grabs and I will detail the windows and doors also. It may be harder to transport but, its alot easier to work with than "N" scale.
Let me know if you want to join the club or if you have more questions.
Mark
