George is correct that a wider gauge would help, and the idea of a
third rail is certainly worth considering, but the other critical
factor is the extent of changes in height and changes of direction -
no train can travel at very high speeds on a line that has fairly
sharp bends. We are more able to flatten out and straighten routes
(albeit atadditional expense) than we were back in the early 1900s,
but we do also have earthquake and volcanic issues to deal with.
It is sad that the oportunity was noit taken to combine a rail upgrade
of the route from Auckland to Hamilton with the construction of the
motorway / expressway - the Auckland / Hamilton / Tauranga triangle is
critical to the movement of freight (both import, export and domestic)
in that area. Transmission Gully involves a steep incline that
probably makes rail along that part of the route inappropriate.
Most large cities have fairly extensive rail passenger transport for
commuters - it is faster and cheaper than roads. Auckland will
certainly benefit from less congestion and shorter travel times.
