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.
