If rail ever gets traction - and surely it must - here is a fine plan. Link Hamilton and Auckland by high speed commuter train. Not some museum rejected diesel gobbling old dunger but a genuine high speed train that zooms through civilized countries. There is one than runs from Paris to Marseille in three hours - nit that we need anything on the scale of a TVG but the speed is not beyond us. Imagine the impact on both cities and the pressure off the infrastructure of Auckland. Don't grow the super city - join it up - intelligently join it up.
