had a crackin mooch here october last yr
seen the control room first hand and the huge fans that control the flow of air
then under the road surface to the tunnel itself
along some escape tunnels to see the cars flying past
also had a look at the service tunnels (central avenue)
well worth paying a visit to this place
a bit of history
airlock door as you enter the chamber..
one of the motors that powers these big fans
and the fan in action...
looking up a fresh air shaft....
one of many escape tunnels...
a little section where you could look through the old dock to the foundations of the cunard building
going under the road surface to the access tunnels
central avenue....under the actual road surface itself
