Stupid gunzel question, is the boiler of 3801 different to the other (former) operational loco, 3830 ??David,
Most will know where I'm going with this.
There has been a lot of information available (both published and unpublished) on the current boiler position for all NSW preserved steam.
In relation to the C38's the only 'spare' boiler is that DB one. The other boilers have tabs that identify their origin (or in this case the loco which each boiler was initially fitted to).
There are currently four reasonably intact C38 boilers. Three are fitted to 3801, 3820 and 3830. There is also the damaged boiler that is part of the 3813 parts collection at Dorrigo.
As part of the post DB boiler return 3 boiler assessment I was informed on the status of the boilers associated with 3801 and 3830. The boiler repaired and most recently refitted to 3801 is boiler tab 3819. The boiler fitted to 3830 is boiler tab 3801 (around 77 years old itself). I do not know the boiler tabs associated with 3813 and 3820.
All four C38 boilers are reasonably identical, that is they were built to the same design. Each boiler as constructed is somewhat unique due to construction and maintenance differences throughout their working lives.
Like any locomotive class the boiler from one C38 was quite often interchanged with another during extensive overhaul. If a spare C38 boiler was available this could be repaired individually independent of an engine. An engine coming in for a major service could be fitted with the spare boiler and the removed boiler thus becoming a new spare and a candidate for rebuilding.
Unfortunately there are currently no spare C38 boilers other than the DB one and the one associated with 3813, which is now owned by Dorrigo, so effectively unavailable as a spare.
THNSW could now build their own C38 boiler from scratch (although unlikely). Word from a recent 3801 inspection is that THNSW want to keep a large loco project going, but want to use 'in house' resources as far as possible. To rebuild boiler tab 3801 it would need to be removed from 3830. Initial work to repair boiler tab 3801 in situ was abandoned as when the boiler work commenced the damage was found to be more severe than what was apparent during the 3 boiler assessment inspection.
We will need to be patient (as was the case with 3801's rebuild) and await a public announcement.
Thank you for this post, seems that some of the previous information regarding the German boiler has as many issues as the boiler itself, a Tornado down under rather than cyclones.
I would repeat something that I was poo pooed on a little while back regarding what you say is the large engine fleet, atm there is really only 3526 in that category but its not really a large engine overall, the closest we would have to a large engine in steam under the THNSW is dead steam 3642, thus the heritage fleet as such is pretty much light on. While 6029 is operational its possibly part of the overall operating steam fleet but who owns it, still in Canberra's listing?
Outside of 3801, there are 2 other 38cl under THNSW control/ownership, but boilers are stuffed, also under their control/ownership are the 3 pigs, 09, 16 & 42. Without doubt 42 has served well and likely more liked by crews owing to the air assisted reversor as against the old heavy originals on the other pair, thing is there is, or were several new boilers that were donated by the railways some years back, how many are any good now is debatable, but the thing is how long can the fleet keep going with so few large engines in the operational listing? I did not mention LVR's 59cl, but they also have an R that's near ready so add two more. Although the garratt and 59cl would have the old 80km/h limitations on them, one would imagine.
I had suggested that if those pig boilers were looked at, and seen as being able to be used as replacements for the 3 pigs, that would increase the numbers of loco's available for use quite a bit, and provide the fleet with engines that adequately share a burden of long distance trips, also would think a bit more economically than 6029.
The aspects relating to 3820 & 30, could well be longer term projects that allow mechanical apprenticeships to be brought in to help into the future, quite a few have been lost after working on 01 at the Dockyard an 30 at East Greta, this is a vg opportunity for heritage to train up people for the future, and that is also going to help keep these old relics going for some time. The idea of in house is great but, having local companies such as the people at Goulburn should also be able to assist in the restoration work of the steam fleet.
Much of the discussion surrounds the boilers of the locomotives and they are critical, but moving away from the 38, 59 & garratt each have cast frames, all the others in the listings have plate frames, which in a way gives some more future proofing should a frame crack, which happened on many steam loco's of all classes, the pigs had their share of, likewise the 32cl. At least with having those classes of loco's in operational condition, it would provide a bit more of a secure future for loco's that can have new frames built if or when needed.
While the NSWGR had its own in house abilities in these areas, they are no longer needed as such those working on 3801 and involved in its restoration at Chullora and at Goulburn are valuable for the future of steam operations for THNSW.
