Yes and when the power failed on the railways, none of the telephones
worked.

Can one still get pp1, pp4 and pp9 batteries by the way?
PP1 were six volt press stud, pp4 round but 9 v press stud either end and
pp9 big 9v for good portable radios.
Also looking for the bijou battery since its used in a vintage torch.

Someone I know well used to trespass on the main East Coast line during
the late 1950 and early 1960s, looking for things to steal. One thing he
found (by smashing a padlock) was a large number of very large 1.5V cells.
They had screw terminals and were connected in series. They were black,
rectangular, about 3" x 3" x 10". They were very heavy but the boy managed
to carry a lot of them home, where he used them to power his spark
transmitter.
