Reading T-1 No. 2100 restoration: Cleveland team shifts from boiler milestones to “making moves” toward excursion service

Published: February 20, 2026

CLEVELAND — One of the most famous survivors of Reading Company’s big, fast freight-era steam—4-8-4 T-1 No. 2100—is inching closer to an operating debut after a restoration that has stretched across a decade and climbed well into seven figures in spending and in-kind labor. The American Steam Railroad Preservation Association (ASR) says the locomotive has already cleared some of the hardest hurdles, including major boiler work and successful steam tests, and is now pushing into the final mechanical frontier: running gear, final assembly, and paint as the engine prepares for break-in runs and, ultimately, public excursions.

Latest Progress

ASR’s most visible milestone to date came in early April 2025, when the organization reported two successful steam test days (April 3–4) at its Cleveland base. According to ASR, contractors and volunteers evaluated the boiler, piping, and water delivery systems during those tests—an important proof-point after years of tear-down, inspection, repair, and reassembly.

The April 2025 steam tests also underscored a major design decision made during the rebuild: converting No. 2100 from coal to oil firing. ASR has described the new firepan and burner as professionally engineered for performance and operational sustainability, and noted that additional drafting work—such as modifications to the blast nozzle and petticoat pipe—was part of the post-test punch list.

Earlier, the project reached another critical threshold when a Federal Railroad Administration-observed hydrostatic test was reported as satisfactory, allowing the organization to proceed beyond the boiler integrity phase and into the systems and operations portion of the restoration.

By late 2025, ASR publicly shifted its fundraising and work messaging toward the locomotive’s running gear—rods, bearings, valve gear, and associated components that will determine how smoothly (and safely) the big 4-8-4 can “make its first moves” under steam. In November 2025, ASR launched a “Making Moves” campaign with an initial goal focused on replacing rod brasses deemed unsuitable for service, while previewing follow-on phases that include main rod work, bearing inspections, alignment (“tramming”), and other running-gear tasks.

What Remains

If the boiler is the heart of a steam locomotive, the running gear is its gait. With steam tests in hand, ASR has characterized the running gear work as the last major mechanical project before the locomotive can move under its own power. After that, the organization says attention will turn to the finishing steps that make an operating engine excursion-ready—electronics, insulation and jacketing, final paint, detail work, and break-in running.

ASR has also been transparent that the final stretch is heavily dependent on contracted machining and professional services. On its website, the group has promoted early-2026 fundraising centered on rod brasses and indicated a larger remaining total still to raise for completion.

#2100's Historical Importance

Reading No. 2100 is more than “just” a preserved Northern. It represents the Reading Company’s wartime/late-war ingenuity: the railroad rebuilt heavy 2-8-0 Consolidations into modern 4-8-4s to create a class of fast, high-capacity locomotives for coal and general freight. No. 2100—rebuilt at Reading’s own shops in September 1945—became one of the icons of that program and later a star of the famed Iron Horse Rambles excursions in the early 1960s, introducing generations of fans to mainline steam in the East.

The locomotive’s preservation story has had as many chapters as its service life. In the 1970s, it became intertwined with Ross Rowland’s American Freedom Train era—serving at times as a parts source for sister engine 2101—before returning to operation in later decades and eventually landing in Cleveland for the current restoration effort that began in earnest after the 2015 move.

American Freedom Train No. 250

A unique twist to No. 2100’s next act is cosmetic—and symbolic. ASR has said the locomotive will wear an American Freedom Train-inspired red-white-and-blue scheme and be renumbered 250, tying the engine to the nation’s 250th anniversary era and echoing the 1975–76 Freedom Train legacy associated with Reading T-1s.
