Union Pacific Unveils 1776 “America250” Locomotive

Published: March 23, 2026

Union Pacific Railroad has officially joined the nationwide celebration of America’s 250th anniversary with the unveiling of a new commemorative locomotive, No. 1776, dubbed the “America250” unit. Announced in March 2026, the locomotive is one of several high-profile initiatives the railroad is undertaking to mark the Semiquincentennial of the United States, alongside special heritage units and a planned coast-to-coast tour of the legendary Big Boy No. 4014.

Union Pacific SD70M #1776, the railroad's official "America250" locomotive. It wears the American flag on the carbody - similar to an earlier livery the railroad utilized - and an "America250" logo on the nose.

A Symbol of America’s Founding

Numbered 1776 in honor of the year the Declaration of Independence was signed, the locomotive serves as a rolling tribute to the nation’s origins and enduring legacy. Union Pacific stated the unit “pays tribute to the signing of the Declaration of Independence and the founding of this nation.”

The locomotive features:

A large, flowing American flag across its sides
Union Pacific’s classic Armour Yellow base scheme
Prominent America250 branding, tied to the national commission overseeing the anniversary

The design reflects both historical reverence and modern corporate identity—continuing Union Pacific’s long tradition of commemorative locomotives that celebrate key moments in American history.

Part of a Broader Commemorative Program

No. 1776 is not a standalone project. It forms part of a broader America250 initiative that includes:

No. 1616, honoring President Abraham Lincoln and the railroad’s 1862 founding
No. 4547, a presidential tribute locomotive unveiled in partnership with Wabtec
A national Big Boy tour, bringing No. 4014 to communities across the country, including a planned appearance in Philadelphia for July 4th celebrations

Together, these efforts highlight the railroad’s historical role in unifying and building the United States—a theme Union Pacific leadership emphasized in announcing the program.

What Model Is UP 1776?

Union Pacific has not officially confirmed the exact locomotive model in its press materials although from the official released publicity photo 1776 is an SD70M. The railroad rosters a large fleet of SD70Ms - originally totaling 1,452 examples - and several have been used as other commemorative units, such as 1616 ("Abraham Lincoln"), 2002 (Salt Lake City Winter Olympics Torch Relay), and 1979 ("We Are One").

Legacy and Importance

Union Pacific’s No. 1776 continues a long lineage of “heritage” and commemorative locomotives, which serve both as public-relations ambassadors and as rolling historical exhibits.

What makes No. 1776 especially significant is its national scope:

It commemorates America itself, rather than a specific railroad or individual
It will likely appear in major public events tied to the 250th anniversary
It reinforces railroads’ central role in the country’s development—from the 1860s transcontinental era to today

In many ways, the locomotive is both a symbol of the past and a statement about the future, emphasizing the continued importance of rail transportation in the American economy.
