Steam & Excursion > SOO 1003 updateDate: 09/30/11 06:47 SOO 1003 update Author: chico Gleaned from a post on the Yahoo WSOR list:
Another FYI, the SOO 1003 is about 65% done. Any one interested can stop by the museum in Hartford , WI . to see the progress of how the group is doing. The goal is to do a test run before the real cold hits to see if anything develops. After that, the engine is going into the WSOR paint shop to be touched up……. ---- chico http://www.heartlandrails.com Date: 09/30/11 10:56 Re: SOO 1003 update Author: Wolfman Wow! That was fast !!

Thanks to all of those involved in the project, my hat is off to you. Karl Date: 10/01/11 10:57 Re: SOO 1003 update Author: mSummers That's great news!

------------------------------------------------------- > Wow! That was fast !! The required 1,472-day inspection is just that, an inspection. How much additional work is required depends on what the inspection reveals. You're always going to have to do a certain amount of disassembly/reassembly just to perform the inspection (e.g., pull the boiler jacket and insulation), but IF you're lucky (or your periodic maintenance is exemplary), it's possible not to have to tear the thing *completely* apart, as you would on the initial rebuilding. Question for those in the know: Do the new regs REQUIRE all the flues and superheater tubes to be removed for inspection, or can you do an in-place examination with video and/or ultrasound and only pull the bad ones?

(a) Inspection of the boiler interior. During the 1472 service day inspection, the steam locomotive owner and/or operator shall remove all flues of steam locomotive boilers in service, except as provided in paragraph (b) of this section, for the purpose of inspecting the entire interior of the boiler and its bracing. After removing the flues, the steam locomotive owner and/or operator shall enter the boiler to remove scale from the interior and thoroughly clean and inspect it. (b) NDE testing. If the boiler can be thoroughly cleaned and inspected without removing the superheater flues, and it can be shown through appropriate NDE testing methods that they are safe and suitable for service, their removal may not be required at this time. Their removal may be required, however, if the FRA inspector, or the steam locomotive owner and/or operator, considers it necessary due to identifiable safety concerns. The reason for removing flues has little to do with the flues themselves. It's about doing an inspection of boiler seams, removing scale, looking for grooving or pitting, inspecting tube plates and the dry pipe, and making sure braces are working properly. To do that, someone has to be able to maneuver inside the boiler. On a locomotive with a Type A superheater, this can usually be done by removing the 2" flues (sometimes called "tubes"), but leaving the 5" superheater flues in place. These days, the 5" flues are a lot more expensive than the 2" flues (I believe they're only made in Germany now), which is the reason for part (b). JAC Edited 1 time(s).

So no painting this year, but that would be done after reassembly.

There is thickness testing, calculations done on the boiler, preassembly steam testing and other things deemed to be in need of repair. Time consuming process for anyone.
