Usually, the Grand Canyon Railway runs from Williams to the Grand Canyon and back (powered by diesel engines using vegetable oil). The train ride on Saturday went only a few miles north of Williams and lasted less than 45 minutes total. Still, it was an incredible experience.
Here's a quick interior shot of the car as we were leaving. These cars were built in the 1920s and are used only for special occasions like this and the Polar Express event during the holiday months.
