Well, I found two fantastic looking stores with one only about 15 minutes from my house. They're going to be able to repair the engine, hook me up with a transformer, power connection, and enough tracks to get me started. I also found the cabooose was missing both trucks, but I was able to find a comparable and inexpensive used car that I can cannibalize for parts. Fortunately, they sell a lot of refurbished stuff to help ease the strain on the wallet. In about a week or so, I should have my set all together and hopefully running without a hitch!
I also did a little research online (thanks to your links) and found out a little more info about my father's old train set. It's a Post War Lionel 1110 Scout Steam Locomotive from 1949-1952, and it was one of their less expensive entry-level sets.
Anyhow, I've had some flooding in my basement, but once that's been addressed in a few weeks, I'm going to get to work on building a table that I can get my set up and running on. Needless to say, I can't wait!
