Does this mean that the Leightonfield sidings will be disconnected from the passenger lines once the SSFL goes through? Note that these sidings have just been resignalled.
Sefton East Junction is very slow (as low at X10 km/h) for Bankstown trains going to Regents Park. If this junction could be rationalised, turnout speeds could presumably be raised.
"The Leightonfield Yard includes an existing electrified refuge loop and
two freight sidings and these could be incorporated into the SSFL and the
existing connections to the RailCorp network would be cut off by the SSFL
alignment. The refuge loop would also have its overhead wire removed.
A separate connection between the two networks would be provided at the
western end of Leightonfield Yard via a long crossover extending from the SSFL east of Villawood (just over 900 metres in length). This connection would enable:
• Freight services to travel between the SSFL and the RailCorp network, via Regents Park, and Lidcombe Loop.
• Freight services with insufficientpower for the Up direction grade of
the proposed Sefton Park Junction underpass to travel through the
Junction on the surface via the RailCorp network.
• CountryLink passenger services (if timetabled) could cross between the
SSFL and the RailCorp network. The long crossover would allow trains
to be parked while waiting for a path to/from the RailCorp network.
Another connection back to the SSFL at the eastern end would allow the long crossover to become a passing loop for parking freight trains while waiting for a path into Chullora."
Railcorp subsequently required the loop lenghthened (westward).
