So I assume its been capped now at the ticket hall level, so that they
can have that newer set of escalators to the north?
But is the shaft completely blocked up, or can you still get to it
from a newer staircase, as, perhaps, an emergency escape?


I must admit, I never actually looked up - mainly due to the smell
inside. It was always more a case of, open door, take a deep breath,
go in, reset the pump and get out before breathing again ;-)

What is it pumping out? (obviously water, but where is it coming from
in such heavy quantities to cause flooding - does the walbrook pass by
there?)

It's the lowest sump of the station. It wasn't down to the quantity of
water being pumped out that caused the flooding, it was the pump
repeatedly breaking down due to being life expired.
