Also acts as recovery time that the train might lose whilst going around the
Bankstown circuit. This standing time was previously at Strathfield, where
Homebush customers complained about the long long wait. So instead of having
that at Strathfield, CityRail moved it to Bankstown, where it might not
inconvenience other passengers as much.

Generally slow trains (those that run on the West Main then Suburban) will
use 3/4, whilst fast trains (those that run on the West Suburban then Main)
will use 1/2

That happens a lot over the Strathfield flyover on the up line, and on the
approach to Burwood station on the up suburban. What is the explanation
there, apart from a huge air gap??? (which I believe there is none).
