Have you ever wondered what’s hidden inside a shipping container as it cruises by on a train? The fact is, it could be almost anything. Whether big-screen TVs or clothing, most of the things you buy came to you via the more than 13 million intermodal containers that pass through U.S. rail transfer facilities each year. In fact it’s the flexibility of these shipping containers which makes this system so powerful and efficient. These containers may look alike from the outside, but inside you’ll find a veritable world of goods. From mattresses to lawn mowers, railroads are efficiently and reliably delivering the products that Americans rely upon every day.
