Re: Concord derailment



Don't forget the famous:
"If the upper yellow functions,
 beware of turnouts points and junctions!"

Which I'm told was actually in the NSWGR rulebook.

<<<<It holds the same force as the Y/G
indication in the VR (US) 'speed signalling' indications, which is a
warning that the next signal is displaying a medium speed indication. No
ambiguity.>>>>>

The US system that Victoria adopted wasn't speed signalling until VR messed
with it and made the bottom light simply mean 25MPH, (later 40KPH) Prior to
this the bottom light meant you were diverging which is still the case in the
US today.

Mark.
