A Union Pacific exec told us why railroads are more high-tech than cars or planes

Machine Vision is just one example of how the freight company, with its expertise in logistics and ability to apply innovations at scale, is leveraging big data-technology in ways that airlines and car companies can only dream of. According to Tennison, Union Pacific plans to expand Machine Vision to 13 portals in total.
Other initiatives include putting the type of track-inspection technology that usually requires specialized locomotives on trains that are plying freight routes every day, greatly increasing the company’s ability to monitor its rail network for trouble…
“We’re aggressive about recruiting top-tier talent,” Tennison said. The company looks to colleges such as Georgia Tech and Carnegie Mellon to tempt science and engineering graduates to take a look at working in the rail industry.
