After we had breakfast with Dave and Lynne (see Dec 25th) we Checked into the Heritage Hotel in Auckland. The Heritage Hotel has had a varied past. It started life as a department store, was then converted to private apartments and then converted to a hotel. We shared a two bedroom suite with Larry and Elaine.
We arrived several days before the tour was to start (most of the people arrived on the 29th). Dave arranged several extra activities for us since we were early.
After we got settled in our hotel room, Joan and Elaine rested in the room while Larry and I were invited for a tour of the high voltage cable tunnel that Dave's company had a hand in constructing. The tunnel is some 10 km long and about 200 feet below the streets of Auckland. It carries a 110,000 volt transmission line into downtown Auckland.
The locomotive on the work train uses a diesel engine with a catalytic converter on the exhaust. Even in the enclosed tunnel there was no smoke at all and very little smell produced. Unfortunately I didn't get any photos of the catalytic converter itself.
The power cables were towed into the tunnel in 1 kilometer lengths. Apparently this was limited by the diameter of the cable spool that could be lowered down the access shaft.
We then walked down to the dock area for lunch and spent the rest of the day generally relaxing.
Next day: December 28
