Hello everyone,
Long time, no update — but that doesn't mean work has stopped in Cleveland! Let's review the latest progress on the 2100.
- Our focus for the past several weeks has been the inspection and testing of the locomotive's superheater units. These units, which raise the temperature of the steam destined for the cylinders, must all be pulled from the boiler and subject to a thorough process of examination, ensuring that each unit is safe for the 2100's next career. As of this writing, 30 of the 50 units have been tested and passed, and we're looking forward to wrapping up this tedious task in the next month or two!
- On average, inspection and testing of a single unit takes our volunteers one hour. Check out our most recent video update for an in-depth look into this process!
- The smokebox has been a beehive of activity ahead of the 1472-day inspection. The petticoat, which funnels exhaust steam up out of the smoke stack, was removed back in April to facilitate the removal of the superheaters and eventually tubes and flues. The petticoat was modified for the locomotive's previous conversion to oil burning, so it will need further attention so that she drafts properly as a coal burner. Forrest Nace photo.
- Since the last post in this thread, many major milestones with the firebox have been met! Projected work on the firebox was completed in late March, and immediately after that, the boiler was put under pressure!
- First up was a low-pressure air and soap test, where the boiler was pressurized to 50 psi and watered-down soap was sprayed over the entire firebox. The formation of bubbles around rivets, staybolts and other welds indicated leaks, allowing us to easily catch problem areas before moving on to the next step. Forrest Nace photo.
- After the leaks identified from the air test were sealed, water was pumped into the boiler and allowed to set, exposing any remaining pinhole-sized leaks in need of sealing. This practice was once performed by the mighty Lima Locomotive Works on their new boilers!
- On April 29, the long-awaited day was upon us at last — the boiler's first hydrostatic test! This test did expose some additional leaks, but this is to be expected the first time the boiler is put under high pressure. Over the next several weeks, the observed leaks were dealt with in preparation for the second hydrostatic test. Speaking of which, that will be coming very soon, so stay tuned to our social media channels for more news on that!
- Once the firebox is watertight, the tubes and flues will be pulled from the boiler for an interior inspection — and you can help us fabricate replacement tubes through our new fundraiser! Starting now, you're able to pledge money to sponsor new tubes, either in one foot segments or in complete 20-foot tubes. Visit our gift shop online to find out more and make your sponsorship today!
- Elsewhere on the locomotive, various small projects are keeping our volunteers busy. The outer firebox wrapper and combustion chamber are receiving new coats of protective paint, as are sections of the running boards. Ultrasound thickness surveys continue in the tight confines between the boiler and the frame. To facilitate the last few readings, additional brackets are being removed from the locomotive to access the boiler shell underneath. The tender was also moved alongside the roundhouse in preparation for further work later this year.
- There are countless ways you can support efforts on the 2100, but one of them could win you $21,000! Our latest 50/50 raffle is underway — half of the proceeds go to the winner, while the other half supports the 2100 and other ASR projects. Find out more here!
- And of course, how could we forget about all that's been going on back east? Since April, the 2100's sister engine, no. 2102, has been rambling again on the Reading & Northern, a Pennsylvania regional railroad which uses original anthracite tracks! Early that month, the locomotive was broken in on caboose hops to various locations on the system, and late April saw the locomotive take on the challenge of a 50-car hopper jet from Reading to Jim Thorpe. Since Memorial Day Weekend, the 2102 has led two Iron Horse Rambles between those two towns, and the third, coming up in just a few weeks, will feature the '02 doubleheading with the R&N's iconic no. 425! American Steam Railroad extends its congratulations to the Reading & Northern steam department for this remarkable achievement, and we look forward to joining our sister engine in steam one day soon!
