potentially a large single track balloon loop from Bondi Junct with three stations. Each station would be a single platform with one being two platforms to allow a short stop of one set to enable time table reliability and train crew rest break.Agree. With regard to the ESR, we've previously discussed options of extending it to Maroubra Junction via Randwick or to North Bondi or both. Now that the metro extension from Metro West has been more or less confirmed to La Perouse via Zetland and Randwick, an ESR extension to Maroubra Junction would no longer be necessary.
That still leaves the option open for the North Bondi extension, whether the locals want it or not. I'd suggest that stations could be constructed at Bondi Road, Bondi Beach (south end), North Bondi and even extend it through to Rose Bay. Think about the traffic, including buses, which would be taken off Bondi Road, particularly on summer weekends.
Similarly, on the Northern Beaches, a rail link would remove the conga line of buses on the Harbour Bridge during peak hours. Agree it should follow the A8 road corridor via Spit Junction, which is a fairly high density area.
Agree, the future metro and LR has deemed the southern fork of the ESR not required.
Back to the beach extension, this is where I think a balloon loop is more viable. I said initially in jest but think there is more to it.
Bondi Jnct station, heading east
- Bondi Road station
, agree on this
- South Bondi Beach
, agree on this
- North Bondi,
probably near Old South Head Road to make bus transfer simple
- Near Rose Bay ferry terminal
- Bellevue Hill (west side of Rose Bay Golf Curse), this is maybe as its 1km to either Rose Bay and Bondi Jct and not needed
This would be all single track, single platform station loop so actual tunnel length is roughly the same as double track but avoids the complexity and need for a turn back. Single TBM project, all spoil removed and materials brought in by rail at night. Apart from one location to assemble and launch the TBM.
However one station would be dual plats island to enable a brief timetable catch up and allow for train staff swap/rest break. The existing turnback at Bondi Jct would be kept and extended to two full car sets.
The TBM would start from either of the storage roads at BJ (project would take over the storage road) and operate from there until the project is complete. The tie in to the other storage road would see half of the stabling siding disabled for a few months.
Why the ferry terminal? It provides PT connect ability with local stations and buses. It also would serve part of the Bellevue Hill area. Overall I think such a loop would greatly reduce the number of buses on local roads.
The issue in the area will be finding suitable locations for stations, despite them being mostly simply lifts and stairs. If RP allowed to upload photos I'd show a under ground Metro station in Dubai, its just four lifts coming to the surface in four locations, basically four corners of the station. Minimises foot print on the surface.
