Culligran Power Station - Access Tunnel Culligran access tunnel is approx. 400ft long, 17ft wide and high, sloping steeply down to the machine hall at 1:10. Except for short lengths at the portal, and where it enters the machine hall, it is unlined. Near the lower end, a passage leading off from the right hand side gives access to the draft tube gallery. Just before it enters the machine halls, two chambers have been excavated on the left hand side for switchgear, office, and a battery room.  Photo: Culligran access tunnel portal Photo by: Mike Ross
