I'm with Joe as far as the excursion part goes. There was a steam locomotive that we rode for about 20 miles out and then back as part of a fund-raiser a couple of years ago. I would do it again but I think watching the engine from trackside is more interesting. Once you start moving it doesn't really matter what is pulling the cars. A steam engine is like a living breathing thing, it is almost better sitting still than when it is moving (I did say almost).
