With Auburn East Junction now commissioned and the associated new signals now in use between Auburn and Lidcombe, I have noticed a number of the new signals that have two lights only, rather than the usual five or six. Quickly passing through, you'd think they were fixed reds, but being on the main line...
Do these signals employ multi-coloured lights? (I know the answer but would like to know more) Is this the first time the former RailCorp has incorporated this technology into its' signalling system?
Regarding this ever-lasting project and thread topic, they are up to stage 9!
