    I heard the new turnback will be in use from 11 January 2014. How will it be used and operated?

    There are of course 2 turnbacks, P2 and P3. These are of course the highly desirable "centre turnbacks".

    During trackwork, trains from the South can terminate in P1, P2 and P3, using the connection along the old Down Main to the New Down Main Bypass.

    Most of the (existing) turnouts at Liverpool appear to be 25km/h types, except the unnumbered divergence of the new Down Main Bypass from the Down Transit Road nearer to Warwick Farm which is hopefully an 80km/h.

    It is not clear if there are enough signals and length of overlap to allow a down train to enter the new Down Transit Road from Warwick Farm while an Up train is leaving P2 or P3. This is allowed at Hornsby and Revesby.

    The total stabling is perhaps 2 trains in the Down sidings, and 2 in the Up siding. The Down Transit Road at the south end might also be used for stabling if there are catchpoints.
