May 10 is National Train Day. The day commemorates trains and their impact on our culture. Trains have paid a huge part in American history. They were the first major connection between the eastern states and the far West. Many of the products that fill our store shelves, the raw materials for manufacturing and the fuel that runs our automobiles are still distributed at least partly by train. Travelling by train used to have a certain mystique: dining cars, sleepers and coaches; the steam whistle sounding in the distance, and the comforting vibration of the wheels on the tracks. Unlike air travel, travelling on trains allowed you to view the passing scenery.
