Chesapeake & Ohio 614 Restoration Pushes Forward

Published: February 18, 2026

STRASBURG, Pa. — One of the most recognizable mainline steam locomotives to survive the post–steam era is steadily moving through an intensive return-to-service overhaul. Chesapeake & Ohio 4-8-4 No. 614, the last commercially built 4-8-4 in the United States, is now deep into a comprehensive restoration at Strasburg Rail Road Mechanical Services, where crews are methodically disassembling, inspecting, and renewing major components with the goal of placing the locomotive back in operation later this decade.

The project is being led by RJD America LLC, which acquired the locomotive in 2024 and arranged its move from Clifton Forge, Virginia, to Strasburg, Pennsylvania, in June 2025—an event that marked the transition from long-term display/storage to an active shop program.

A famous “Greenbrier” returns to the shop

No. 614 is part of the C&O’s J-3a “Greenbrier” class—C&O’s preferred name for its 4-8-4 type locomotives, borrowed from the famed West Virginia resort on the railroad’s main line. Built by Lima in 1948, the engine’s short first career in regular service ended early in the diesel era, but its second life in preservation would prove unusually prominent.

After time in museum custody in Baltimore, 614 eventually became the centerpiece of several high-profile outings. It ran on Chessie-era publicity trains, took part in the 1980s “modern steam” coal tests as 614-T, and later gained new admirers hauling mainline excursions on New Jersey Transit in the 1990s—among the last times many fans saw a full-size 4-8-4 stretch its legs on a busy passenger railroad.

That history is a big reason the current restoration has generated such intense interest. For many observers, 614 isn’t simply another display locomotive getting attention; it’s a proven mainline performer with an established “brand,” capable—if the restoration succeeds—of returning to the kind of high-profile excursion service that has become increasingly difficult to mount in the modern regulatory and railroad-operating environment.

Ownership change and a decisive move to Strasburg

In November 2024, Railfan & Railroad reported that RJD America LLC had acquired the locomotive from Iron Horse Enterprises and Ross Rowland, announcing that the engine would be rebuilt at Strasburg. The organization did not disclose project funding details publicly, but projected an operational return on the order of a couple of years at that time.

The physical relocation followed in June 2025. Railfan & Railroad described 614’s departure from Clifton Forge via the Buckingham Branch Railroad and Norfolk Southern before interchange for the final segment into Strasburg’s orbit—symbolically important because it placed the locomotive at one of North America’s most experienced steam repair facilities, with the workforce and tooling to tackle a “top-to-bottom” rebuild.

What’s been done so far: disassembly, evaluation, and the start of heavy boiler work

By early 2026, the work had advanced well beyond cosmetic stabilization. In a February 2026 update, Trains reported that 2025 was heavily focused on disassembling, evaluating, and cataloging components after the locomotive’s arrival at Strasburg—exactly the time-consuming, documentation-heavy phase that sets the foundation for a compliant and durable rebuild.

Among the most significant milestones cited:

Cab removal: The cab has been taken off the boiler, improving access for inspection and repairs.
Boiler internals opened up: The superheaters and tubes have been removed, allowing needle-scaling and detailed internal work.
Air system teardown: Both air compressors were removed and disassembled, part of restoring the locomotive’s air and braking reliability.
Appliances and auxiliaries in progress: Shop teams have been taking apart locomotive appliances as the rebuild advances into deeper mechanical territory.

The locomotive’s official restoration updates, published by the project team, reinforce that 2025 ended with “systematic disassembly, inspection, and documentation” indoors at Strasburg—exactly what you’d expect as a major steam locomotive transitions from assessment to corrective work.

Replacing staybolts

If there is one element of the rebuild that has become the public “headline,” it’s the decision to replace a large number of flexible staybolts—critical boiler components that support the firebox sheets under heat and pressure cycling.

The locomotive’s official restoration page states that thousands of flexible staybolts are being systematically removed and replaced as part of documented, federally regulated boiler restoration work during 2026.

While the FRA condemns flexible staybolts below 65% of original metal thickness, the project team raised its internal threshold to 75%, a more conservative standard intended to increase the margin for longevity and reliability once the engine returns to service.

To help finance this portion, the project has also promoted a “Buy A Staybolt” program, offering a limited number of retired components with certificates of authenticity while funding one-for-one replacements—an approach that blends fundraising with tangible artifacts for supporters.

Next major steps

While a great deal has already been accomplished, the 2026 plan includes several high-effort tasks that often define whether a restoration stays on schedule.

On the official restoration page, the team notes preparations to lift the locomotive so that all wheels can be removed, enabling replacement of the tires on all driving wheels—a major milestone for any large steam locomotive returning to mainline-capable mechanical condition.

Key items on the “to-do” list this year:

Extensive firebox sheet replacement
Jacking up the locomotive to pull and rebuild running gear and trucks
Developing a dual Positive Train Control (PTC) system incorporating I-ETMS and ACSES, an ambitious step aimed at expanding potential operating compatibility in today’s PTC-governed territory.

That last point is particularly notable. PTC requirements have become one of the biggest barriers to widespread mainline steam operation, and a dual-system approach signals that the organization is thinking not just about getting 614 running, but about making it practical to route the locomotive across multiple host railroads and corridors—if agreements and operating plans can be secured.

Timeline: a Summer 2027 goal

Restoring a 4-8-4 is never a small undertaking, and both the project’s public communications and outside reporting emphasize that the work is being treated as an exhaustive rebuild rather than a quick turnaround.

In its February 2026 report, Trains stated the project remains on a timeline aiming for Summer 2027 as a completion goal—described as a goal rather than an absolute promise—while also stressing the team’s desire for a “top-to-bottom” restoration.

The official restoration updates likewise present 2026 as a “critical phase” focused on long-term safety, regulatory compliance, and the heavy mechanical milestones that turn a dormant artifact into a reliable operating locomotive.

Looking ahead

Among preserved steam locomotives, C&O 614 occupies a rare niche. It is historically significant as a modern "Super Power" Lima-built 4-8-4, and culturally significant for its unusually visible preservation career—from Chessie-era publicity to the famed ACE tests to mainline excursions that helped define what modern steam could look like in the late 20th century.

Just as important, the project is unfolding in an era when bringing large steam back to life is tougher than ever: FRA compliance costs are high, specialized labor is scarce, and mainline access is constrained by modern dispatching, liability concerns, and PTC. In that environment, the combination of Strasburg’s proven shop capabilities, an apparently well-organized ownership group, and a strategy that includes a support fleet and PTC planning has made 614’s return-to-steam effort one of the most closely watched restorations in North American railway preservation today.

If the current pace and funding hold, 2026 appears set to be the year No. 614 transitions from disassembly and documentation into the kind of visible “put it back together” progress railfans love—new firebox work, rebuilt appliances, renewed running gear, and the long march toward a fresh hydro, a first light-off, and eventually, the sight many have been waiting decades to see again: a Greenbrier Northern at speed, under its own steam.
