Re: [NSW] Tangara Derailment , Hornsby

["Chris Downs" <cvdowns@ozemail.com.au>]

I take Dr Morals' point that speculation can be dangerous but I think less
so than silence as long as we don't delude ourselves that every utterance on
aus.rail is truth.  A "closed shop" approach will not make this issue
disappear.  The Daily Terror and the SMH will not lift their game in
relation to reporting incidents factually and in full just because aus.rail
ignores such issues, and I sincerely doubt that aus.rail rates as a
significant source of intelligence.  The media will retreat when the
incidence of reportable incidents dries up.

In the interim CityRail must resolve the issues and deal with these
issues/incidents openly and expeditiously whilst keeping the media and the
public informed.  Its far too late and far too much has happened for silence
to do anything but encourage increased media and public cynicism.

Regarding what happened at Hornsby the other evening I've been informed by a
source that I consider most reliable that the T-set came from Berowra into
platform 3 (up main).  It then reversed and proceeded northwards past HY55
over 522 points which were reverse for a move set from no. 2 platform - so
the lead bogie trailed through the points.

In an attempt to try to retrieve the situation, the train was then driven
back towards the platform. The lead car's second bogie was on the station
side of 522 (on the up main) and the first bogie was on the northern side
with the points still reverse, i.e. set for number 2 platform. The result -
Sydney end bogie to platform 3, country end bogie to platform 2.

Finally, if there is a consensus that these issues should not be discussed
on aus.rail I will comply - over to you.
