I bought my first Diesel today when I drove by Jims Train Shop in Homer City.http://www.jimstrainshop.com/xcart/customer/home.php A trip to Jims is great even when you don't buy anything. This is my first DIESEL that I have ever owned. It is a MTH SD-9 "Pennsylvania rail Road" I now love the power of two percision flywheel motors along with two powerful fan enhanced smoke stacks. I think my line up of steamers may be in trouble. This engine has tons of power and if you want it can crawl slower than a turtle. There is just a ton of value in this $250 SD-9 Diesel. Now I want the unpowered unit and another Diesel or two or three or !!!!!!!!!! The big O 3 rail train line is growing.
