What do people think about the plans for the remainder of the T3 line after the Bankstown metro becomes a thing? The preferred option is pic related, but I think they should just leave it as two shuttle services from Bankstown to Liverpool and Lidcombe (ie. option 1). That way you don't need to build a new wye track and you actually free up City Circle slots for the other lines. Otherwise your dumping even more trains onto the main trunk line.
