dom and the vent hole at copthall

hello, short video looking at the dom position its nose is over land, and the vent hole at copthall , vent number 1 or Barry is looking very smart , looks almost complete, now lets cover it all in mud...... going back soon for a closer er look at it, and the dom in a few days, Tuesday yes Tuesday will be my next visit and will post up some more detailed shots of IT, ohhh just noticed the tunnel has a slight curve as well, guess it sets up the train for a nice long right hander towards the chiltern south porthole , nice one

Lovely, and may your air hole vents always be with you, and yours....😊...🌬️...

[@SIMONC256]

one thing in life you can always trust is your air hole, when its needed it's there, never late or in a rush, on time and ready, hopefully these one's perform as well

Big ones always have big holes.

[@raymondflanagan9355]

Why is that vent hole so massive?

[@williambryan3372]

The vents were all sized to allow the tunnel to be naturally ventilated by airflow over the landscape mound, rather than use any mechanical equipment on site :)

[@NairdA1983]

Also to release the pressure from train entering the tunnel
