In an electrified railway tunnel, would water be a safe fire extinguisher?
I assume yes, because outdoors these systems are safe in rainy conditions. How would one determine the water delivery rate required (formula please).

NO water is not a good extinguisher!
Fires in an electric rail tunnel are mostly likely to be electric fires (of class C). Dry powders are the preferred extinguishers.
A typical dry chemical extinguisher containing 5 lbs. of ammonium phosphate dry chemical.
Electric Fires are usually caused to incidents like short circuits! Rain water doesnt act like a fire extinguisher. Refer wiki for further detials if required !

Water would be unsafe to use in an electrified tunnel. It may cause short circuit in the electric trains. It would be safwer to use Dry chemical type fire ectinguishers.

the idea that the flames have no oxygen so a powder or foam is the best solution water is only used in less confined spaces. it can make matters worse and cause other problems.
