ok then. so what would happen to the tube if london's power got cut? im
guessing theres no auxillary system in place....is there? i think i
remember
something about them having their own fossil fuel power generators...



Does anyone remember a major power cut on an early weekday morning sometime
in the mid 1990s on the Underground ? If I remember it right it was caused
by a cable failing somewhere near Blackwall which fed the eastern end of the
Central line, and the subsequent surge on other parts of the supply system
caused a domino effect of fuses tripping until the whole system was without
power. Supplies to traction, station lighting, signalling were lost. Most
of the system got going again later in the day (early afternoon?), although
the Central line east of Liverpool Street did not run for a further 5 days
or so.
