The Far Western Sub-Corridor commences in Melbourne and heads north utilising the existing Melbourne to Albury Line as far as Mangalore. The Sub-Corridor can then follow two alternative alignments between Mangalore and Junee via Albury or Shepparton. The Albury alternative utilises the existing Melbourne to Albury Line through to Albury with a deviation at Wodonga and then the Main South Line from Albury to Junee; or The Shepparton alternative follows the existing broad gauge Mangalore – Tocumwal Line via Shepparton that will require dual gauging. This alternative then follows the disused Narrandera – Tocumwal Line to Narrandera with potential deviations at Finley, Berrigan and Jerilderie. At Narrandera the Sub-Corridor utilises the existing Junee – Hay Line to Junee. At Junee the Far Western Sub-Corridor can follow several routes to connect Junee to the Stockinbingal – Parkes Line: From Junee the Sub-Corridor follows a section of the existing Main South Line from Junee to Cootamundra with potential deviations including Bethungra and Frampton, then utilises the existing Cootamundra – Lake Cargelligo Line to Stockinbingal ultimately connecting into the Stockinbingal - Parkes Line; Route Option 0201 utilises a direct route from Junee to Stockinbingal connecting into the Stockinbingal - Parkes Line; or Route Option 0101 utilises a direct route from Yeo Yeo on the Cootamundra – Lake Cargelligo Line to Maleeja on the Stockinbingal - Parkes Line From Stockinbingal the Sub-Corridor follows the existing Stockinbingal – Parkes Line to Parkes, then utilises a short section of the Orange – Broken Hill Line to Goobang Junction with a potential bypass at Parkes. From Goobang Junction the Route Option follows the existing Parkes – Narromine Line to Narromine. At Narromine the Far Western Sub-Corridor can follow several route options: From Narromine the first option follows the Main West Line from Narromine to Dubbo, then the Dubbo – Coonamble Line from Dubbo to Coonamble with a potential bypass at Dubbo (Route Option 0304); Route Option 0301 utilises a direct route from Narromine to Armatree connecting into the existing Dubbo - Coonamble Line; Route Option 0302 from Coonamble to Burren Junction, then follows the existing Narrabri – Walgett line from Burren Junction to Narrabri with potential bypass of Narrabri (Route Option 0308) connecting into the existing Werris Creek - Mungindi Line to Moree; or Route Options 1401 and 1402 from Coonamble to Narrabri via Gwabegar, then connects into the existing Narrabri - Walgett Line. 10.7 - 2 ACIL Tasman | Hyder Consulting From Narromine the Sub-Corridor follows the Main West Line from Narromine to Dubbo, then utilises the existing Troy Junction – Merrygoen Line (with several potential deviations), the Wallerawang – Gwabegar Line (with potential deviations), Binnaway – Werris Creek Line to The Gap (with potential deviations) and the Werris Creek Mungindi Line from The Gap to Moree with a potential bypass at Narrabri (Route Option 0309); Route Option 0501 from Binnaway to Boggabri on the Werris Creek Mungindi Line; or Route Option 0601 from Premer on the Binnaway – Werris Creek Line to Gunnedah on the Werris Creek – Mungindi Line. From Moree (Camurra) the Far Western Sub-Corridor follows the existing Camurra – Boggabilla Line to North Star. At North Star the Sub-Corridor follows a section of disused Camurra – Boggabilla Line to Doyles Siding, then follows Route Option 0401 from Doyles Siding to Kildonan on the existing Warwick – Dirranbandi Line The Far Western Sub-Corridor follows the existing Warwick – Dirranbandi Line to Inglewood. At Inglewood the alignment has two alternatives: At Inglewood the alignment follows the existing Warwick – Dirranbandi Line to Warwick, the Toowoomba – Wallangarra Line to Toowoomba, then the Ipswich Toowoomba Line to Grandchester. The existing narrow gauge lines will require dual gauging; or Route Option 0402 from Inglewood to Millmerran, follow the Wyreema – Milmerran Line (to be dual gauged) to near Toowoomba and connect to Route Option 0403 Gowrie to Grandchester. The Far Western Sub-Corridor follows the existing Ipswich – Toowoomba Line to Calvert. At Calvert the alignment has two alternatives: Follow the existing Ipswich – Toowoomba Line, the existing Brisbane - Ipswich Line, the existing Yeerongpilly – Corinda Line which will all require dual gauging. The alignment then follows the North Coast Line south to Acacia Ridge; or Route Option 1301 from Calvert to Kagaru on the North Coast Line, then follows the existing North Coast Line to Acacia Ridge. 10.7 - 3 ACIL Tasman | Hyder Consulting Figure 1 - Far Western Sub-Corridor 10.7 - 4 ACIL Tasman | Hyder Consulting A total of 20 improvement options have been identified for the Far Western Sub-Corridor as described Table 1. Concept designs have been developed for each route option in accordance with the infrastructure criteria to enable indicative costing of each option. To identify the route options with the best value for money, the Study Team determined the minutes in transit time saved per dollar spent for each project. The results of the analysis are provided in Chart 1. The route options that yield the maximum improvement in travel time per dollar spent are: 0901 Finley – Jerilderie (Greenfield) 0903 Tocumwal – Junee (Berrigan Deviation) 0902 Tocumwal – Junee (Finley Deviation) 0101 Yeo Yeo – Maleeja (Greenfield) 0906 Tocumwal – Junee (Junee Bypass – Narrandera to Stockinbingal) 0907 Mangalore – Tocumwal (Murchison Deviation) Chart 1 – Improvement Options (Value for Money) – Far-Western Sub-Corridor Time Savings per Dollar Spent Far Western Sub-Corridor 2.5 2 1.5 minutes/$m 1 0.5 0 0101 0102 0201 0202 0204 0301 0303 0304 0308 0411 0901 0902 0903 0904 0906 0907 1201 1401 1501 Route Option Note - Route options with a Time Saving per Dollar Spent of less than 0.02 min/$m have not been included. 10.7 - 5 ACIL Tasman | Hyder Consulting Table 1 - Improvement Options – Far-Western Sub-Corridor TRANSIT LENGTH PROJECT TIME ROUTE NAME OPTION COST $000 (NEW COMMENTS DESCRIPTION SAVING TRACK) (MINS) Proposed alignment provides a direct connection from existing Cootamundra - Lake Cargelligo Line at YEO YEO - 0101 GREENFIELD 12.7 25,501 13.00km Yeo Yeo to near Maleeja on the Stockinbingal - MALEEJA Parkes Line bypassing low speed curves at Yeo Yeo and the township of Stockinbingal Proposed alignment on the Cootamundra - Lake YEO YEO - Cargelligo Line removes low speed curves at Yeo 0102 MALEEJA 8.2 126,020 19.30km Yeo and Stockinbingal with reconfiguration of DEVIATION turnouts at Stockinbingal to connect into the Stockinbingal - Parkes Line Proposed alignment provides a direct connection from Junee on the Main South Line to Stockinbingal JUNEE - on the Stockinbingal - Parkes Line bypassing low 0201 GREENFIELD 52.3 120,166 50.40km STOCKINBINGAL speed curves and steep grades at Bethungra Spiral, the township of Cootamundra and low speed curves on the Cootamundra - Lake Cargelligo Line Proposed alignment removes low speed curves and steep grades at Bethungra Spiral, low speed curves at Frampton, Cootamundra on the Main South Line and JUNEE - Yeo Yeo and Stockinbingal on the Cootamundra - 0202 STOCKINBINGAL 35.0 1,104,651 74.20km Lake Cargelligo Line.
