Headed into the 1920s, the Florida East Coast felt like they were on top of the world. They had completed their successful Key West Extension and were capitalizing on the Florida real estate boom. They double-tracked their mainline from Jacksonville to Miami and placed large orders for Mountains and Pacifics, including the #148. And then, they got hit by the 1929 stock market crash followed by the Great Depression, and then in '35 a hurricane wiped out their Key West Extension. Suddenly the FEC found itself in financial dire straits and had a surplus of motive power. They began selling off large amounts of steam locomotives. Many of their Mountains went south to Mexico, where some operated as late as the '60s. They also sold off a number of their Ten-Wheelers and Pacifics, which found new homes on short lines.
Enter US Sugar in Clewiston, Florida. Tired of relying on trucking companies to move sugar cane from their fields to their plants, US Sugar laid down 25 miles of track and began their own internal rail service. Needing locomotives, and not wanting to spend money on brand-new engines, they purchased some FEC 4-6-0s and 4-6-2s. These locomotives were light enough to serve their needs, and with a relatively short (for a Pacific) 68" driving wheel, they weren't high-speed sprinters. A comprehensive steam roster for USS is difficult to find, so exactly which engines they owned is a bit hard to find, but they had at least 5 Pacifics (#65, #98, #113, #148 and #151) and at least one 0-8-0 (#253)
The #148 was not one of the Pacifics sold off in the '30s and '40s. It held on on the FEC until dieselization started in 1952, at which point US Sugar grabbed it up, presumably to replace one of the Ten-Wheelers (of which none survive) or one of the earlier-purchased Pacifics. USS kept the steam engines on the job until the late 1960s as they had an advantage over diesels: in the event of a flood, you could still operate a steam engine over flooded tracks, while a diesel would ground out the traction motors. But by '68, the steam engines were largely relief power and they sold them off. The #113, #151 and #253 went to museums, but the #148 went north to NJ.
The #148 began an excursion career, first on the Black River & Eastern and then on the Morristown & Erie. But by this point, it was a 50 year old steam engine that had been used hard for a long time. Firsthand accounts from crews say that by this point it had lots of leaky flues and dry pipes, and the wheel flanges were worn thin to the point where they had a bad tendency to pick switches. In 1977, the Morristown & Erie cancelled their steam operations and the #148 was retired. It then ping-ponged across the US to various owners, all of whom planned to restore it but then discovered the extremely poor mechanical condition of it. In the 2000s, it ended up in Colorado, where a company was trying to start up a tourist dinner train program. The #148 was torn down and disassembled and found to be in incredibly bad shape, with the boiler down to 1/4" thickness in spots and the tender rotted out, and then the 2008 recession killed off what seemed to be its last hope.
But in 2016, US Sugar purchased the remains of the #148 and shipped it back to Florida and began an exhaustive restoration. As one person described it "I had the chance to see this engine while it was in Traverse City, MI in the midst of an aborted attempt to restore it. I can't think of an engine in worse condition where an operational rebuild was attempted. For example, I am sure you could have punched a hole right through the rusted-out tender - so a new tender tank is absolutely needed. And the engine appeared to have many parts missing on the backhead and running gear. Also, I was told the engine was dragged en route to Traverse City, damaging the wheels and who knows what else more. So I am not surprised the 148 needs basically everything rebuilt new or from scratch - running gear, wheels, drivers, backhead, cab, etc. I am still surprised anyone attempted this restoration."
The restoration was originally undertaken by a contracted team, but as costs mounted, USS let them go and began using their own employees. Typically a change in crews is the death knell for a restoration, but not in this case. The #148 received a new boiler, new firebox, new front flue sheet, a new smoke stack, new cab and windows, new valve gear crossheads, new side rods, new drive wheels and bearings, overhauled lead and trailing trucks, a new tender cistern and oil tank, essentially everything. And along the way, they threw in a number of upgrades, including cross-compound air pumps, roller bearings on every axle, non-lifting injectors and brake handles on the tender. Essentially, aside from the frame and lead and trailing trucks, they damn near built a new locomotive from the ground up.
Current operational plans are a bit nebulous, but I'm sure now that she's operational, they'll start announcing whether they will be running public excursions or not. I'm interested to see if maybe a trip over the Florida East Coast trackage is in the future.
