Lithgow is still a contentious Seat for both State and Federal with a very long Labor History and the Seat could change 'tomorrow'.
I believe its utterly ridiculous to think that this new rolling stock was ordered without knowing what sizes were what!!
When the Blue Mountains was Electrified 60 years ago, the Tunnels were skinned and many adjustments made to line side infrastructure to allow both the 46 class and the Single Deck Interurban's to run.
This had to be done again with the introduction of the Indian Pacific and the opening of the Standard Gauge to Perth via Parkes and Broken Hill.
As an aside, had the line NOT been upgraded but sent via Melbourne to Adelaide to Perth, would we still have a line west of Mt Victoria or Lithgow?
I still feel strongly that given the slightest chance, all Interurban Electric Passenger services would terminate at Mt Victoria and all the Bus' servicing all but the Broken Hill Line would commence from Mt Victoria despite what has been spent at the New Station.
