Efficient and secure railway operations are vital to the global economy. Railways transport billions of tons of freight and passengers every year across thousands of miles of tracks, linking municipalities and countries. To put it in perspective, the U.S. alone moves over 1.6 billion tons of freight on more than 140,000 miles of track annually, including 1.6 million tons of raw materials and consumer goods. However, due to the sheer number of freight cars moving every minute of every day, mishaps and system failures are common occurrences.
