Big Boy 4014 · 2026 tour archive
Seven milestones that made the completed 2026 program unlike prior No. 4014 runs.
Before the 2026 run, No. 4014 had not visited Indiana, Ohio, New York, or Pennsylvania. The eastern leg, from May 25 through July 29, took the locomotive into new territory.
Union Pacific and Norfolk Southern formally co-publicized the eastern routing. East of approximately Chicago, the train used Norfolk Southern track, including former Conrail and Reading-heritage routes no Big Boy had previously traveled.
On June 15–16, static Big Boy No. 4012 at Steamtown National Historic Site in Scranton was displayed alongside operating No. 4014. The locomotives had not been together since ALCO built them in the early 1940s.
Review the Scranton stop archive →No. 4014 crossed the 1854-built Horseshoe Curve on July 11, adding one of the tour’s most significant railroad-landmark passages to the historical record.
Review the archived route →On June 13, No. 4014 crossed the 240-foot-tall, 2,375-foot-long Tunkhannock Creek Viaduct at Nicholson, Pennsylvania. No Big Boy had made that crossing before the 2026 tour.
Union Pacific organized the tour around the United States’ 250th-anniversary period and introduced commemorative locomotives No. 1616 and No. 1776 as part of the broader program.
The western leg ran from March 29 through May 24, followed by the eastern leg from May 25 through July 29. Earlier No. 4014 tours had focused on a single region rather than a season-long, coast-to-coast program.
