Returning to KingsX just now it stopped at Copmanthorpe for several minutes at the crossing, blowing off. Then restarted and continued on it's way. A great show to watch....and the noise.
Does anybody know why ?.

because the driver shut off steam and applied the brakes?

arr' , devilment on behalf of the footplate crew - to condensate the OHLW's ,you know the rest


mr B

suprized some university graduate has'nt worked out the corrosive acids to the wire's caused by smoke/exhaust gas's from coal fired propulsion.

SO2 + H2O = H2SO3

Pleas explain that to a semi educated 83 y/o

I believe (O Level Chemistry, 1982) that it shows that steam locomotive exhaust contains Sulphuric Acid.

I always thought sulphuric acid was H2OSO4

waffle can anyone tell us why she stopped?thank you

manners learn to punctuate and use capital letters thank you

Well as nobody seems to know, here is a pic of it stopped and blowing orf, just downloaded
from my camera device. Must say some very interesting replies.

Apologise if my sense of humour took this thread off topic. But sulphur dioxide (SO2) + water (H2O) = sulphurous acid (H2SO3). More water and the appropriate heat, would create Sulphuric acid (H2SO4) + Hydrogen (H2)

Hence Network Rail don't allow steam engines to stop under OLE, connections, neutral sections, etc., except under exceptional circumstances.

Silly question - any signals about? Or perhaps they were advised over their radio to slow down, due to a train in the section ahead?

Any number of reasons, but it's unusual to get a full stop in a section without a signal and a restart, I'd have thought?

Yes there is a signal a bit further on but it was green all the time. I'm told it only goes to green when the route is set at Colton junction before the train leaves York, but I will double check this. No train was in section before it as the section ends just out of view.

4 aspect signalling all through there.

Maybe the driver was topping his railway issue watch battery up with the sulphuric acid ?
