On Wednesday, a Union Pacific \u201cBig Boy\u201d ran by itself on the main line for the first time since the steam era thanks to the installation of a new Positive Train Control system.<\/span><\/p>\n

Earlier this week, the railroad announced UP 4-8-8-4 4014 would make a brief test run out of Cheyenne, Wyo., but an exact reason for the test was not given. But on Wednesday, <\/span>photos and videos of the move posted online<\/span><\/a> made it clear that UP was testing a new PTC system on the locomotive. Previously, UP used something called \u201cLeaPTC,\u201d which required it to run on the main line with a diesel locomotive. But now 4014 has PTC installed directly on it meaning it no longer will need to operate with a diesel (although it\u2019s unclear if UP will let the locomotive venture too far without a diesel just in case mechanical issues crop up). The system is similar to one<\/span> installed on Canadian Pacific 4-6-4 2816 last year<\/span><\/a>. Like 2816, the PTC equipment has been installed in a cabinet in the tender.\u00a0<\/span><\/p>\n

In 2019, when 4014 first returned to the main line after an extensive restoration, UP had gotten a waiver from the Federal Railroad Administration to let it run on PTC territory without the technology. In 2021, it became the first main line steam locomotive to receive the technology<\/a>.<\/p>\n

UP 4014 will depart Cheyenne on June 30, as part of a <\/span>month-long tour of Wyoming, Utah, Nevada, California and Idaho<\/span><\/a>. The locomotive is expected to run again in the fall, venturing to Texas, Arkansas, Kansas, and Illinois, among other states.\u00a0\u00a0<\/span><\/p>\n
