So apparently you can charter international tours via restored, vintage steam powered locomotives.
I figured it was of course an aesthetic choice to use a steam powered train of yester-year in the film, but I also didn't assume this was impossible to actually do in real-life. Thusly, I had to look it up
Never tried chartering a steam railway tour...you would need quite a few folks to make it work financially I imagine. A better option might be taking one of the established steam railway tours. Last year we slurged and traveled on the The Trans-Siberian Express. Unbelievable fantastic, a 15-day journey spanning two continents and seven time zones! A good, well established organization for finding out about railway tours is Society of International Railway Travelers. They list many steam railway tours all over the world. Another railway tour, one of the unique Attractions in Las Vegas is the Historic Grand Canyon Train Tour. We found discount tickets at Free Things to Do in Las Vegas as well as lots of self guided walking tours.
