The more containers that can fit on a ship (measured in 20-foot equivalent units, or TEUs), the cheaper it is to move them. Today, the Triple E class container ships built for Maersk Line are the world’s largest ships. The Triple E class can hold 18,000 TEUs, enough to transport 111 million pairs of sneakers, or enough to shoe over 1/3 of the U.S. in a single trip. The Triple E is 1,300 feet long (which is the height of the Empire State building), 194 feet wide, and 240 feet high.

As ships bring bigger swells of goods and ask for quicker turnaround times, the ports are focusing on how to get those goods off the ship and on the roads or rails faster. So while ships are maximizing economies, ports are focusing on efficiency. At this point, rail proves to be the most efficient mode of land transport. In 2013, railroads moved a ton of freight an average of 473 miles on a single gallon of diesel fuel. Rail is widely considered to be 3-4 times more fuel efficient than trucks, and especially vital for moving bulk cargo—2/3 of U.S. coal shipments move by rail, for example.
