I thought that the tube had emergency lights (well the signs on the 1992
stock say so!)

They are only of limited use, allowing people to see a little.

As for stations (in the central area) originally there had to be two
sources of electricity (Lots Road and Greenwich in later years) by
law. This was revised in drawing up the PFI deal and the stations
were fitted with battery powered emergency lights.
