Union Pacific's 3-D Printing Revolutionizes Railroading

Omaha, Neb., June 7, 2017

While NASA is finding ways to use 3-D printing technology to provide necessities for colonizing Mars, Union Pacific is applying the same technology to make locomotive operations safer and more efficient. The railroad’s efforts and early successes with 3-D printing are outlined in a new Inside Track story published today on the company’s website.

The article includes perspectives from several employees intimately involved with 3-D printing, including System Engineer Royce Connerley, who explain how the technology enhances turnaround time for models and prototypes.

"Printing 3-D prototypes in-house accelerates our rate of change," Connerley said. "We can make modifications during multiple iterations without waiting for each version to be returned from an external vendor."
