Gold Coast Line 12tph - CONCERNING - requires the Kuraby to Beenleigh track upgrade (or slowing down of Gold Coast services). 8tph more likely.
Beenleigh Line 4-6tph - NO IMPROVEMENT
Salisbury (future Beaudesert) Line 7tph - CONCERNING - requires suitable turn back facilities at Salisbury and scheduling concerns i.e. interactions with other lines. Limited possibility of service improvements after Beaudesert Line opens due to the lack of a 4th track from Dutton Park to Salisbury.
Ipswich and Springfield Lines 12tph (each) - CONCERNING - requires European Train Control Signalling (ETCS) from Darra to CBD, and ideally 4th electrified track and platform through Oxley. Not dependant on CRR.
Ferny Grove Line 8tph - NO IMPROVEMENT - ETCS would improve reliability on core section.
Caboolture and Redcliffe Lines 12tph (each) - CONCERNING - requires ETCS from Petrie to CBD, and ideally improved track layout at Kippa-Ring. Not dependant on CRR. 4tph on Sunshine Coast Line.
Shorncliffe Line 6-8tph - CONCERNING - 6tph requires duplication between Sandgate and Shorncliffe (or complex timetabling with poor reliability). 8tph from Northgate to CBD is no improvement, and ETCS would improve core system reliability.
Airport Line 4tph - NO IMPROVEMENT - ETCS would improve reliability on core system.
Doomben Line 2tph - NO IMPROVEMENT - to not extend to Hamilton Northshore is a disgrace.
Cleveland Line 11tph - CONCERNING - 11tph from Manly to CBD would require a 3rd platform at Manly. No improvements proposed from Manly to Cleveland. Express services will probably be eliminated.
15 minute off-peak services - CONCERNING - off-peak service proposals are not even published by CRR, and running 4tph throughout the suburban network would be constrained by multiple infrastructure limitations including lack of 4th track on the Beenleigh Line corridor.
Sufficient Trains - CONCERNING - approximately 40 new trains are required to optimise peak services on the existing train network and for additional peak services for CRR. These have yet to be ordered.
Sufficient Train Crew - CONCERNING - sustained driver recruitment and forward planning is required.
Tunnel stubs for linking to future NWTC / Trouts Road Line - CRITICAL - not in current plans. To attach these tunnels would require a closure of CRR for many months.
To conclude, other than lines where there will no improvements from Cross River Rail, all other lines are currently in the CONCERNING category as they require either new track infrastructure that has not started construction, new signalling that has not been implemented, more trains that have yet to be ordered, and crew that have yet to be employed. CRR's opening may be 5 years away, but the clock is ticking. Many of these scores may change to CRITICAL if there is no action by this time next year.
