'T 'H E possible consequences o f a sudden black-out are too serious for London T ransport to risk a breakdown in lighting. As a safeguard against an interruption o f the mains supply P. & G. Batteries are installed to supply emergency lighting to the stations and certain sections o f the tunnel automatically and on the instant any such interrup
tion occurs. On the Leytonstone tube extension, four sub-stations—
Leyton, New bury Park, Leyton
stone and Redbridge—are equipped with P. & G. Batteries, each com
prising 120 cells w ith a capacity of 400 ampere hours in 10 hours.
P. & G. and E.P.S. is a name backed by 60 years’ practical experience o f this type o f work.
W ith P. & G. Batteries in reserve
—London’s new tube lighting is as safe as hum an ingenuity can make it.
