New Hampshire Boiler Projects

I remember last summer there were a few updates on some steam locomotive boiler projects in New Hampshire. One was the re-boiler-ing of the geared locomotives at the White Mtn. Central and another was the repairs to the existing boiler of Conway Scenic’s 0-6-0. Any updates on these projects? Will there be steam in the White Mountains this year? (excepting the Cog Railway of course).

From the Conway Scenic Web site:

LOCOMOTIVE #7470 UPDATE 1/4/2006

CSRR is in receipt of a letter from FRA approving our welding plan for proposed boiler repairs to #7470. With this approval in hand we will resume 7470’s repair program. Boothbay Railway Village, our boiler contractor, expects to have their crew back at work in North Conway before the month is out. They will weld the needed flush patches in the corner of the firebox and as part of those repairs will drive half a dozen hot rivets in the mud ring. Non Destructive Testing of the Welds will be completed once the replacement segments are in place. After the weld testing is done and we have passed a hydro-static test and, provided no further problems are found, we will begin the task of putting #7470 back together for service.
Thank you,
The management, CSRR

I am most curious as to why there will be NDT of welds made on a patch located within a stayed area?

The WMCRR Climax has her new approved boiler and after reassembly of the locomotive this winter/spring, should be percolating this coming operating season.

The fellows from Boothbay Railway Village have been in North Conway five days a week for the past few weeks working on the 7470's boiler. They're staying there this weekend and I think the inspector may be there next week.

Thats great news, somehow I missed the 7470 blurb on the CSRR website the first time around. I'll be visiting these places in August and hope to see the finished products, especially the boiler on the climax.

Thanks for the responses.
