Re: Light rail fails in the hour of need

Considering the less than 2 km distance between Moore Park and Central,
there was no problem with the number of six artics that would have filled
up the available road doing a continuous loop. The event buses actually
have a dedicated loop terminus at Moore Park on the site of the old tramway
loops and where a loop should have been built for CSELR event trams! The
issue is that the buses were supposed to supplement the trams, not do the
whole job for them! The other thing is that the bus loop is out of sight of
the tram stop, so most people would have gone to the tram stop and waited
there in the rain, unaware that there was a duplicate bus service from a
well-sheltered stop nearby. Poor design and poor management. I guess next
time we'll see everybody who learned from experience heading for the bus
terminus and ignoring the tram.

The other issue is that, in spite of knowing that there would be 30,000
people at the venue, TfNSW didn't consider it necessary to authorise
additional LX trams to infill between the regular trams. Even in the event
of the points failure, I believe that was further upstream, so the LX trams
would have been able to continue operating even if the regular route trams
were held up.

As an aside, I do wonder how they go with running LX trams in between the
regulars at a combined 2 minute headway, considering the shunting required
at the event stops. Do they really manage to trundle one of those 67 metre
trams into a siding, get the driver to waddle the distance to the other end
(on the ground, considering the tram is a coupled set), go through the
startup procedures and run back into the platform two minutes before the
next regular tram arrives? This is why, in the early planning, in lieu of
loops, we recommended triple platforms at Circular Quay and Central, while
others and I urged for loops at Moore Park and Randwick Racecourse. The
railway types, in their wisdom, thought that shunting stubs would be OK at
the two venues. Unfortunately, I don't live there to observe how this goes
in practice, but the way the trams trundle around generally, I can't
imagine it happening with the precision of a Swiss watch. Perhaps this is
why TfNSW doesn't encourage the use of extra event trams - they've learnt
that the operation has a good chance of stumbling over itself.

On a side note, the reason for the third platform at Circular Quay was to
provide for a future two-minute headway operation. The third platform
should be permanently empty under the current 4 minute service, but I hear
reports that there are sometimes three trams parked there. Now how would
this happen I wonder? (Guessing the answer.)
