Did you check to plans to see if it will fit?That's a good question Neil.

Clarifying a bit. I was mentally including the HR aspect in the Dollar issues. The only way this could ever happen is in a supported environment, eg thinking back to the 3801 Hunter Valley Training Coy type of thing. I don't have any of this type of engineering expertise or access to drawings. I do know in other fields that things never designed to interface can be made to interface when they are of comparable size. I ask the question here knowing there are some who can speak to the idea. There exists one new boiler and two/three static/unspoken for locos, so can something be done to use these? The usage I was thinking of was day trips from Sydney to the Illawarra/Short South, Blue Mountains and Newcastle.Fit the now homeless boiler to a 59 cl frame??? 5908, 5910, 5916? It's capable of generating more than enough steam. Adjust and balance to make it a 100Kmh or greater runner. It could be great tour loco.Definitely Number Three.

Herein lies this erroneous assumption that all you need to do is throw dollars at something and it'll work out OK. Thats what went wrong with the first boiler. The truth is, the environment in which we train people to do this work no longer exists - so it doesn't matter how much salary you want to attach to a position when you advertise it, you will still not get anyone answering the position because people with those skills simply no longer exist - and never will. Unless we're willing to create a new NSWGR then wait another 10 to 20 years while the shed cleaners filter through and pop out the other end as train crew and railway engineers, HR will forever be the primary challenge of running any heritage rail operation.Clarifying a bit.

From my very limited knowledge I was expecting what a6et said about efficiency. I also can remember riding in a 59 at 15 secs to the 1/4 mile and needing to hang on.
There are still competent professional engineers (at least here in Victoria) but they have two disadvantages:Herein lies this erroneous assumption that all you need to do is throw dollars at something and it'll work out OK.

Even the "3801 Hunter Valley Training Coy type of thing" was 30 years ago.
So unless you're willing to pay a few billion $ to create a world where these people can gain experience, you can't "include the HR aspect in the dollar issues" anymore.
Because no amount of dollars can buy skills that simply no longer exist.

- They cost money because they know what they are doing and they also know what needs to be done.
- There are not based in NSW.
One of the problems is that a blend of skills are now needed at both an engineering level and at a trade level. The advances in welding now permit repairs that would never be allowed or attempted back in the steam era. Assessing what can and can't be done to a steam loco boiler relies more on recent welding engineering knowledge than steam age riveting knowledge. Then, again,when a riveted lap seam is replaced by a butt weld the tensile strength across the join will be as good as the parent metal, but how do we assess the loss of stiffness that the riveted lap seam added to the boiler?Agreed.
Old boiler people are a reticent lot and for good reason, they know full well the dangers of stepping outside tried and true practice.

So what we're facing in modern railway preservation is a situation where new, un chartered engineering takes place. A situation where neither the old hands nor the new generation can quite wrap their skills around the situation.
In effect, it's necessary in many of these cases to start again from scratch. Neither the old nor the new work methods can be used - a third and quite complex blend of both is called for.
This sort of thing of course was done back in the past too.. but in that case we had 100's of locomotives, huge workshops and entire teams of full time engineers, often with unique and specialised experience, to wrap their heads around the various problems. In these environments, problems could be worked on in parallel - where many problems could be solved concurrently.
Now? We're trying to restore a mere single locomotive, in a small workshop with a team of mostly volunteers each with their own varied experience. Everything is done in series and step by step. Sometimes in this process we step through the project only to discover later that something was missed or we need to change something that happened a few steps back. And the only way we can change that is to actually make those steps back, unravel the knot and then do it again.
Putting deadlines on such projects is absolute folly.
As for welded repairs, as everyone knows when you weld something and then it cools, it moves. In new designs you can allow for this in the cuts and jigs but when mixing new and old, it all becomes a matter of individual fit - any kind of plans or measurements get thrown out the window.
A few micrometres in a seam can mean an error of a whole millimetre at the other end of the boiler and a situation where nothing will fit.
I don't envy their job. I'll stick to my electrics.
Yes, and that's one of the reasons why they were chosen.
As I understand it, the boiler is being repaired by a team of professionals in Goulburn.
They have built and repaired boilers for years.
Was anybody able to attend the advertised Q&A session during the heritage expo? Were there any interesting insights provided?No, but I had a long talk with John S on F1 beforehand and he basically spilt all of the beans + more while we yelled at each other over the racket of Sydney 3000 series red set motors.
November update:And that's the way you do PR. Minimal words, a few good photos, and most people are happy.

There are some comments on Facebook regarding the quality of the welding shown in the last image of the firehole.What specifically are they saying?
It is anticipated that this welding will not pass inspection and is substandard for this application.
I am not wanting to get into a pissing contest over these comments as they are not mine, just pointing out that some people with more experience and knowledge of welding and boiler work are astonished at this work and commented so.
