Thanks for pointing that out. I didn't notice the small print. I interpret that to mean that Waterfall will now have 4tph in the peak, all going to Bondi Junction, including the South Coast Thirroul service, and a new South Coast express service to ST will be added to bring it up to 4tph. Have I got that right?The "+ 4 services at Sutherland * " has an asterix denoting one extra South Coast service being included in that number.
So that's two extra from Cronulla, one from Waterfall and the one South Coast.
And two extra from Hurstville (thus adding up to +6 * )
I was confused by the diagram showing 6,000 more 'customers', i.e. 5 additional trains, on T4 to Bondi Junction, bringing it up to 19tph, when in fact it's really 4 additional trains (ex Cronulla and Hurstville) with the SCO Thirroul service being retained. The other 3 SCO trains will be diverted to ST plus the 1 additional SCO express service.
I wonder if the SCO Thirroul service to Bondi Junction will be retained when the NIF is rolled out on the South Coast. They could use 6 or 8 car NIF sets or convert it to a suburban service with 8 car Waratahs or Tangaras. The latter would only be suitable for those with healthy bladders.
