Union Pacific

Congress and federal authorities have expressed their interest in some level of automatic train control (ATC) for more than a century.

The nation’s railroads have made significant strides implementing Positive Train Control (PTC), a former Federal Railroad Administration (FRA) administrator says.

Union Pacific’s historic steam locomotives, Big Boy No. 4014 and Living Legend No. 844, will join together in a public display for the first time May 9 in Ogden, Utah, coinciding with Union Pacific’s celebratory event marking the transcontinental railroad’s 150th anniversary.
