There are 6 pumps at Hay street.  4 normal pumps, and two emergencies.  There are two tunnel
pump chambers at Erskineville with (I think) 4 pumps in each.  There are two pumps at Chalmers
Street (near Platform 25)  There is the Hay street pumps between Central and Town Hall.  There
are pumps between Town Hall and Martin Place.  There are pumps between Kings Cross and
Edgecliff.  There are pumps between Town Hall and Wynyard on the City Outer.  I can't think of
any others off hand...

The rail level is approx 10 metres below sea level, with the bottom of the pump chamber going
down to 14 metres below.
