Fantastic shot!  Like it a lot and it's great in black and white.

HEHE thanks, yes no injuries, made the day more exciting, had to walk a few km to nearest town. But just a normal day in Africa, someone stole part of the train tracks

Yikes! 

I wonder who determined that the steam locomotive was safe to be around.  I can see vapour at extreme right, an indication that the boiler is under pressure.  With the engine tilted onto its side, the crown sheet inside of the firebox is exposed partially, and will be above the water level in the boiler.  If there's still a sizeable fire in the firebox, the crown sheet could melt and the boiler contents will explode outward, expanding 1600 times its liquid volume.  Yes, steam expands at least 1600 times when it is released to atmosphere if it is contained in a pressurized vessel.

I love that you know that --  or even if it is just that you know enough about the equipment involved to track down the information. I always thought I was just here to learn a little about photography but I often learn so much more. Based on the earlier post it appears all involved remained safe in this incident, but it is also always enlightening to see lesser precautions at play in other parts of the world and to appreciate the confy world I live in.

Hey this is Africa, not many rules and regulations, we're tough, lol. We were standing there around the train for about an hour and there was no police or emergency services. So we all just started walking to the nearest town, which was our destination anyway, Just a few km's.

Trip was to a small mining town called Cullinan. The place where the worlds largest diamond was discovered. Pieces of this diamond is part of the British crown jewels.

We just carried on with the day, did some sightseeing. had lunch and then by the afternoon they at least organized us some busses to take us back the 80km to the train station where our cars were, The date on pics is not correct, my son was not even born yet, hehe don't know if if was even married yet. It should be more somewhere 2010-12.

Sometimes you do feel safer with many rules and regulations, but it can also feel like less freedom?

And to give some perspective. Nobody was really angry or wanted to sue or anything, it was quite exciting.

A few years later we went on the same trip on the same train. On our trip back the afternoon the train ran out of coal, halfway back and we sat there for a few hours in the bush next to the train, waiting for another locomotive to come tow us back. That time everyone was up in arms and angry at the operators, demanding money back etc.

Thanks for fleshing that story out for me.  It saddens me to see such a lovely steamer tilted over like that.  Although, I appreciate the shot of the drivers, frame, brake rigging, and equalizer apparatus (levers and fulcrums that act like a suspension to keep even pressure on the rails).

It isn't a rule so much as it is an ethical and safety concern.  Usually an overturned steamer runs a high risk of boiler explosion for the reasons I stated.  The firebox and flues near the fire are more than red hot, but the boiler's rear actually surrounds the firebox.  It keeps the hot roaring fire from melting the steel.  When the boiler's water level is lowered too much, the roof of the firebox, known as the crown sheet, is exposed solely to the firebox's heat, and it will soften and blow into the firebox from the pressure above it in the boiler.  As soon as the hot water is allowed to escape, it sublimates into steam at normal atmospheric pressure, and it will kill anyone in the cab behind the firebox.  But, if the explosion is really large and catastrophic, it will do more damage and possibly injure people rushing to help.

I'm glad you were able to rescue yourselves and to enjoy the rest of the day, albeit with a bit of a hike thrown in.

Built in 1884, this is a "Water Balanced Funicular".

It is now the oldest water balanced funicular still in operation in Great Britain, linking the Victorian town of Saltburn with the only remaining pleasure pier on the whole North East and Yorkshire coast.

Each car has a water tank and they are connected by a cable. The tank of the car at the top is filled with water, while the car at the bottom has its tank emptied. Then gravity takes over and the heavier top car goes down while the lighter bottom car goes up.

I'll run this mini-challenge until Monday, 05 June.

Southern Railway 630, a 1904 product of the American Locomotive Company (ALCO) Richmond (Virginia) works strutting its stuff at the ripe old age of 114, as captured by my Canon PowerShot S110:

The steam locomotive hazard

Yikes!

I wonder who determined that the steam locomotive was safe to be around. I can see vapour at extreme right, an indication that the boiler is under pressure. With the engine tilted onto its side, the crown sheet inside of the firebox is exposed partially, and will be above the water level in the boiler. If there's still a sizeable fire in the firebox, the crown sheet could melt and the boiler contents will explode outward, expanding 1600 times its liquid volume. Yes, steam expands at least 1600 times when it is released to atmosphere if it is contained in a pressurized vessel.

Insofar as the locomotive is on its side, the risk of failure may be less in the crown sheet--which is at the top of the firebox--than in the right side sheet (quite possibly fully exposed). And it's better but here worse: commonly crown sheets contain fusible plugs, which are designed to melt before the sheet fails, sending steam into the firebox and extinguishing the fire; but I'm not aware of side sheets having fusible plugs.

Of course a steam locomotive boiler explosion is a very bad thing, quite likely to kill anyone nearby and quite capable of killing people far away, so better safe than sorry. If the locomotive crew was not too injured, they should have made sure everyone was clear of the immediate area and then done something to release the pressure in the boiler. With common boiler pressures of not-super-ancient steam locomotives running about 175 to 250 psi (1.2 to 1.7 MPa) and superheating being more the rule than the exception on operational steam locomotives, there's a lot of energy = potential for trouble in that boiler.

Does it count as a special kind of "transportation"?    (Taken by Canon G1X III)

Yes, it counts.  Thanks for posting.
