Locomotive 3001 to be restored to steam

  studdo Locomotive Fireman

I hope a6et keeps using the acronyms. It's wonderful seeing things from a railwayman's perspective, a bit like trying to preserve an otherwise lost language. Not many are hard to figure out. I even had a fair idea of what a snotty nose  was (for once, I was right). So keep it up a6et.

By all means use the acronyms, but also print what they mean. Kids like studdo can amuse themselves trying to guess; us oldies would like to know for certain.

A boiler in daily service for 19 years obviously hasn't been through that many heating and cooling cycles.

Again you miss the point. Boiler water treatment is hardly ever going to be perfect. Yet you can have perfect water treatment and a boiler, particularly a firebox, will still deteriorate. Heritage locos naturally go through many heating and cooling cycles from sporadic operation. No amount of careful treatment and washouts preventIs the corrosive effects of fuels and combustion.

I've volunteered at a heritage railway with a boiler water treatment plant more advanced than a modern drinking water facility. They still have their own boiler shop, they still have to rebuild boilers every ten years or so and they will go on doing so as long as they continue operating conventional coal-fired steam.

What you seem to be implying is actually dangerous.
OK Mr Fish, firstly a little background about me, Worked as a fulltime Fitter/Machinist for the last 17 years for 2 Heritage Rail Organizations one mainline, one tourist railway, Volunteered for 3 more in addition to those who I have been employed by.

Over those years I have seen the effects of incorrect/ineffective and No Feedwater treatment in both boilers in daily service and infrequent use, and in all cases If you get it right corrosion and scale disappears, this is no pie in the sky stuff it can and has been demonstrated many times in the past.  

With regards to the use of sophisticated plants I would argue that this is not necessary as there is an old saying that goes "it's not what your putting in the Boiler that matters, it's what's in it" and if there are still being rebuilt every 10 years said plant has been ineffective.

There used to be some good articles an Feedwater Treatment here https://5at.co.uk/index.php/modern-steam-2/principles-of-modern-steam/porta-s-water-treatment.html bottom of page but no longer working.

There is plenty more info out there for those willing to look for it and learn from it.

In ending I find your comment "
What you seem to be implying is actually dangerous." extremely offensive and insulting.

You are still ignoring everything else that impacts a boiler's life apart from water quality. That is what is dangerous. I'm not looking to offend you but to caution everyone from a laissez-faire approach to safety. We can't develop an attitude where we say boilers can stay in the frames until a major failure. A boiler should be lifted and rebuilt at an appropriate interval as determined by usage and condition to allow proper inspection and repair if necessary. This could be ten or twenty years or any other amount of time but it will fall due for every boiler. That is why such works are stipulated in many boiler codes.

Some organisations may see their boilers last decades without the need for many heavy repairs. Others will not and it is not solely down to effective treatment. The boilers where I have worked are in much heavier usage than just about any in Australia, except perhaps Puffing Billy, and are all riveted in construction, not welded. Many of them come out of service with water spaces in good condition from proper treatment but fireboxes requiring significant repairs. For example, riveted seams can only be repaired with patch screws whilst the boiler is in the frames so many times before they reach their condemning point. They then either need to be disassembled, the holes patched up and re-riveted or the plates replaced.

Having been a member of the RTM since 1971 I hardly qualify as a kid, but as a pun on snotty nose I'll take it as a compliment, Valvegear.

A major update from THNSW, a steam test was conducted yesterday

From their Facebook page
Locomotive 3001 underwent a steam trial today for the first time since 1998, marking an important milestone in bringing the 117 year-old engine back to life.

Overhauled auxiliary components have been refitted to the boiler, including air compressor, injector valves, superheater elements, steam pipes and lubrication lines.

Next step in the project is to continue the rebuild of the tender, and to refit the cab, pistons and motion to the locomotive prior to further testing.

Great to see the project finally getting some attention
