On a typical day, quite a few trains roll by the museum hauling nothing but oil from end to end. When you stop to think about how much oil one of these trains is actually transporting and that another one of these trains will be passing by before long, it adds up pretty fast.
These two photos are of the same train taken a few seconds apart, the first photo pointing east toward the front of the train and the next one pointing west toward the rear, showing what is probably a hundred cars or more moving east toward refineries. Many people have no idea how much oil the USA produces, but a day spent track side at the museum will open their eyes.
If you come to the museum you'll be able to watch the incredible variety of goods moving by train on the very active tracks just a few feet away, cars and trucks, food and fuel, everything the economy produces, it's quite a sight. Be sure to bring your camera, there's no telling what you'll see while you're here.
