Railroads are a key link in the supply chain of the goods we need every day. Today's train's cargo consists of containers, loaded at the Port of Oakland, bound for Union Pacific's Global 3 Intermodal Facility just outside of Chicago.
Railroading is truly a marvel of engineering that is a product of foresight. Today's modern train retraces much of the same route built by the original Transcontinental Railroad in the 1860's.
The flanged wheel carries a train the same way it did nearly 200 years ago. That is truly an invention that has stood the test of time.
