->greyhoundollie The air is warmed by compressing, but by the time it makes its way through a hundred feet of exposed hose and then when the pressure is released into the hat it comes out quite cool! You head is not generally touching the hat so there is little conduction there. For cold water you rug up in thermals and work hard!

Rug up!
I do that just getting to work...

Built as standard gauge series number 2 of the FAIRLIE ENGINE AND STEAM CARRIAGE CO. LONDON.
"Double Fairlies" were articulated, all wheel driven mostly for steep, small radii narrow gauge railroads.
The first delivered were to Ffestiniog Railway in Wales. (Note 1)



#2 was delivered as Nässjö-Oskarshamns Järnväg's locomotive #1, bought and renamed "Hultenheim" in 1874. (Note 2)
It was owned and used by the contractor, Morton's, for building the very same railroad during its first years.

32 years later, at 11.25 AM on Tuesday, April 8th 1902, this had happened:



-What series of events led to a 28+ metric ton locomotive levitating upwards, out of its shed
and plummet down on a small hill 25 metres away?

Closest shed brick wall is gone, the other propped up, the ceiling blown off.



Amazingly, no one of the seven persons in the shed was killed in the accident.
Casualties:
C.M. Sand, Chief Engineer (also young stoker at the top pic) had one lower leg broken off and lacerations.
J. Nilsson, Supervisor, also suffered a leg broken as well as lacerations.
C. Petterson, lacerations and concussions from getting hit by flying wooden beams from the former ceiling.
So - what happened, and why?



The #1 loco have had a 30 year service, and was overhauled at Eksjö to finally become a shunter.
Note the boiler pic above - rather two boilers back-to-back with a firebox each.

Hot pressure testing had started without realizing that a lead washer,
used from the previous cold pressure test to protect the gauge, was still in place.
-Did I forget to mention the safety valves had also been firmly tightened down?
This washer apparently had a smallish pore in it - as the gauge climbed during firing,
finally to set at at an comfortable 8 atm (130 psi) in spite of further stoking.

This continued for a good while, but when the Chief Engineer perceived something was very wrong,
and finally yelling for the fire to be put out, the loco took off thru the ceiling, just leaving its two drive bogies behind.



-Why UPWARDS, you probably ask?
Seems like the 2 boiler ends towards the fire boxes gave in (or rather out), converting the superheated liquid water
into a pillar of expanding steam going downwards, blowing away the grates and ashpans, lifting the upper loco part,
tearing off the steam tube bogie pivots leaving the cylinder frames on the shed's track.
View from below, upwards into the fireboxes:



Boiler explosions from firebox failures in ordinary locomotives usually result in more horizontal missiles:



But as the Fairlie had two boilers back-to-back, the steam had nowhere else to go but downwards,
thus raising the loco up, up and away. Pretty simple, eh? Case closed.

-Now try to figure out the reasons for this pic from Strömmen, Norway in 1889:



Thanks for putting up with my story this far!

DIY Swede, thank you for the detailed history! I had the pleasure of riding the Ffestiniog Railway in 1985...of course with no knowledge other than it went UP with great power...we toured thes slate mine, and I, in my would be explorer mind (32), decided the fast way down was overthe side, rather than wait for the train...well, the 'side' was the steep embankment, 1:1, of slate slag, for about 400 mtr...my my...I did not beat the train...if you get the chance, Wales has heaps of attractions to explore, none better than Port Merion, the model Italianate village used in 'The Prisoner' series with Patrick McGoohan and his Lotus Super 7...well worth watching...#6...cheers from the fire raveged South Coast of NSW, AUS...

That is indeed a fascinating account of the "flight of Fairlie". All of those old engineering marvels fascinate me.

Unsupervised work crew! (no one in a suit and tie!)

That's a real testament to the coopers of the area! The whole thing is sitting on 8 or 9 barrels. I wonder how many times they crawled under it!? I love the little Irish guy on the right in the back! How do I know he's Irish? Just look at him!

When start to think of them building that, one of the first thoughts is, how did they drill all those holes? Did they match drill them. Or were they that good they the parts could be pre-drilled, then assembled like that and the rivets still fit. Always amazing to see the old photos.

I wonder why the guy smoking a pipe standing left of center has a bullet hole in his hat?
