    Posted in General » Are Australian cities really implementing a metro system?

    The option of terminating the Airport train at St James isn't a bad one, would need about 1.5km of tunneling and a new station at Pitt Street.

    Just to expand on that.  My initial thoughts were to divert the Airport Line at Central to the unused U/G platforms 26 & 27 and continue on to St James.  Being on the upper level of the station box, it wouldn't be too steep a dive from the existing tunnel portal under Prince Alfred Park.  However, regrettably, part of platforms 26 & 27 are to be used for plant and services for the new metro, so that option is effectively cut off.  It's a shame they didn't have more foresight and left the option open for future use of the platforms for a new rail link.

    The advantage of extending the Airport Line to St James and removing it from the City Circle is that it takes the line further into the CBD where it can terminate using the unused centre platforms.  There's already a turnback in place.  This would allow for cross platform interchange to and from the City Circle, or it could even continue around the City Circle in the off-peak.
