Here's
my chance to bore you with my holiday snaps.
I'll start with why I was in
New Zealand. My day job involves designing Traction Power Systems for
electric railways with a particular specialisation in computer modelling
of the power supply. In Wellington they have a 1500v DC suburban network
that they are about to spend a load of money on to upgrade it and add
new trains to.
To support that process I was
out there to model the power supply as it is now, add the new trains and
then expand the power supply to cope with them. The first two pictures
are the
apartment where we were staying - they're trolley bus wires - and then
view from the office window. The window was in the left hand side of the
building in the back ground of the picture on the right.
Both sorts of the existing
trains can be seen in this next picture. The red one is a 1952 built
English Elec tric
unit. This particular one is tarted up to make something off it being
the last one built but there are plenty of them still running. Passenger
growth has been such that some have even been fetched back from museums.
The other tr ain
is a Ganz Mavag built unit dating from the 80's and allegedly paid for
with sheep! Of course playing with these is perfectly acceptable as they
are narrow gauge as all the main lines are 3'6" gauge!
This graph to the left is
just a small example of the sort of thing I do. It shows the simulated
output of one of the sub stations. It shows the peak and average loads

That's enough of the boring
work stuff. Whilst in Wellington I managed to spend some of each weekend
exploring railway stuff locally. Towards the end of my stay Annie came
out to join me and then we managed a two week holiday and did a week on
the south island before returning to tour the north - we barely
scratched the surface and want to go again. |
