60007 Why did it stop

[quote="Si."]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)

you fail to mention copper ?

Any Sulphuric acid remaining on the OLE would react with the oxidised areas of Copper wire, and form Copper Sulphate and water. The water would then react with the Copper, forming Copper Oxide, which would react with the Sulphuric acid, and on and on.

Given sufficient Sulphuric Acid, the OLE would be covered in a blue salt for a period, before becoming so thin it sags and wraps itself around a passing pantograph. Unless it all gets washed off during the great British summer weather...

Can't help you with 60007, but IIRC, BR tried Aluminum wire for a while, on it's overheads for a trial period, don't know the outcome, but they did go back to copper, but I wonder how it reacted with the exhaust from a steam loco !

PS, I parked my old Ford Zephyr at Rochford station for years, it used to get coated with copper dust, once a year I had to rub the car down with 'Ajax' to get it off

Sulphuric Acid resulting from steam engine exhausts would dissolve Aluminium, leaving Aluminium Sulphate and hydrogen. Which would be good for the trackside vegetation.

Maybe the AWS 'horn' went off and the driver was slow to cancel it?.

On Diesel & Electric locos sometimes trains stop in signal or block sections for no apparent reason cos the driver has 'dropped the DSD' accidently i had it happened last week where i am.

So long as the crew haven't been eating beans or mushy peas......

Heard from someone 'inside' that driver contacted signalman and reported 'air issues': Someone 'pull the chord' ?
