NPS Awards $1.93M To Sioux City Railroad Museum

Published: February 18, 2026

SIOUX CITY, Iowa — The Sioux City Railroad Museum has received a $1.93 million National Park Service grant aimed at pushing the museum’s long recovery from the June 2024 flooding into a new phase—one that tackles both repairs still out of reach and the larger challenge of protecting the historic site from future high water.

Announced in January, the funding comes through the National Park Service’s Emergency Supplemental Historic Preservation Fund Disaster Grant program, intended to help historic places recover after disasters while also supporting mitigation work that reduces the risk of repeat damage.

For the museum, the award is a major milestone after floodwaters inundated parts of its campus—most dramatically the roundhouse, where images from June 2024 showed water surrounding equipment inside the historic structure.

What the grant will support

The funds are earmarked for both ongoing flood recovery and future mitigation at the museum’s home, the Milwaukee Railroad Shops Historic District. Museum leaders have said the grant will help address recovery items that had remained beyond reach since the 2024 disaster and move the site closer to full historic preservation goals.

Trains.com reported that more than $1 million of the total will be directed to the restoration of Great Northern 4-6-2 No. 1355, a signature artifact for Sioux City and the broader Midwest preservation community. Additional grant dollars are expected to assist with restoration work involving a diesel locomotive, the museum’s roundhouse and turntable, and other track and site needs.

Public radio station KWIT summarized the announcement as an inflection point—nearly two years after the flood—giving the organization the resources to accelerate improvements and strengthen the museum’s resilience.

About The Museum

The Sioux City Railroad Museum is not simply a display yard—it occupies the remains of a once-bustling industrial railroad complex. The museum sits on the former Chicago, Milwaukee, St. Paul & Pacific (Milwaukee Road) shops property along the Big Sioux River, a site that grew into a major repair and servicing terminal during the steam era. The complex is now recognized as the Milwaukee Railroad Shops Historic District, listed on the National Register of Historic Places.

The historic district encompasses a broad railroad landscape with surviving buildings, structures, and associated resources. Preservation advocates have noted that it represents one of only a small number of surviving roundhouse-terminal landscapes in the United States, underscoring why major repairs and flood protections are so important to the museum’s long-term mission.

The site’s railroad history is also tightly tied to Sioux City’s own rise as a rail hub. Historical summaries note that Sioux City grew into a significant rail center in the early 20th century, and the Milwaukee Road’s decision to build a major shop terminal there left behind the physical plant that later became the foundation for today’s museum.

Flood Recovery

When floodwaters swept through in June 2024, the impact was not limited to cleanup. Museums face a layered challenge after disasters: protecting historic structures, stabilizing artifacts, and restoring public access while maintaining safety and preserving integrity. The Sioux City Railroad Museum’s own public messaging has noted that it has been undergoing continued restoration and renovation as part of its post-flood recovery, affecting operations and access.

That is what makes federal preservation dollars so pivotal: they help cover the kinds of specialized work that can be difficult to fund through admissions, memberships, and local fundraising alone—everything from structural repairs to site systems and protective measures.

While the grant announcement in January highlighted recovery, it also underscored the forward-looking theme of mitigation: not just fixing what was damaged, but strengthening the site against the next extreme weather event.

Great Northern 4-6-2 No. 1355, “Chief Ironhorse”

If one artifact symbolizes Sioux City’s rail preservation work, it is Great Northern steam locomotive No. 1355. The museum calls the engine a highlight of a visit—an early 20th-century locomotive originally built in 1909 and later rebuilt by Great Northern into a more modern configuration, with the engine recognized for its mechanical and technological significance.

Separate from the museum’s general site story, Project GN1355 has drawn regional attention because the locomotive is being pursued for a return to operation. The project’s website describes the effort as a revival campaign, tracking progress while acknowledging that timelines in heavy steam restoration are complex and dependent on resources. Trains.com reported that more than $1 million from the new grant is slated to support the 1355’s restoration work.

Visiting and supporting the museum

In addition to its large artifacts, the museum promotes programs and exhibits intended to bring the region’s railroad history to life. Due to recovery work following the 2024 flood, the museum has indicated that access and operating status may be limited or adjusted while restoration and renovation continue. For supporters, the new NPS grant is a meaningful vote of confidence in the museum’s long-term value—not only as a place to see preserved locomotives and railroad equipment, but as a steward of a nationally recognized historic district.
