Proposed track amplification projects

Since opening as a single track railway in 1857, various track amplification projects have been proposed for the Geelong line.

1969 Melbourne Transportation Plan


The 1969 Melbourne Transportation Plan was a road and rail transport plan for Melbourne, the state capital of Victoria, Australia, instituted by Henry Bolte's state government.

  • Construction of two new tracks between North Melbourne and Footscray.
  • Third track between Newport and Footscray. The first part of the plan was completed in 1976.

2000 Fast Rail to Regional Centres feasibility study


Early planning for the Regional Fast Rail project also examined the creation of express tracks for V/Line trains through suburbia, which was detailed in the Fast Rail to Regional Centres feasibility study final report released in September 2000.

  • Option MG4 – Upgrade the Main Goods Lines to Docklands.
  • Option MG5 – Upgrade Main Goods, Outside Goods, and the Dynon Flyover.
  • Option MG6 – Realign Champion Road Junction.
  • Option MG7 – Third Track from Laverton Junction to Aircraft.
  • Option MG8 – Suburban Operations into Werribee.
Option MG8
Scope Description

Currently this section of track is a conflict point, significantly for all up suburban trains and down country trains. In addition all suburban trains oppose at this junction.

This option provides a third track from Laverton junction, past Laverton and Aircraft stations. This option allows extended sections of loop and parallel working and thus reducing the timetable conflicts that may occur in this section of track. The layout removes the suburban/country opposing move and removes the suburban opposing moves on the main line. The layout does not remove the opposing moves on the existing single line section on the Westona loop.

Effectively the short loop on the suburban system just on the Up side of Laverton junction is extended through Laverton and past Aircraft station. A dedicated high speed track is thus provided as a bi-directional track for peak flow direction high speed. Country services in a counter peak flow are directed onto the appropriate Up or Down suburban track as a following move.

High Speed (100kph) crossovers are proposed (1in24 tangential turnouts) where a country train needs to be redirected. All other turnouts and crossings are proposed to be 1 in 15 for 65kph operation.

The existing goods siding is rebuilt as the High Speed track. At Aircraft the station is rebuilt to allow the third track to pass without increasing the width of the road crossing at Aviation Road.

The level of protection at Aviation Road is not proposed to be changed owing to the following;

· no significant change to the number of trains is currently proposed;

· the line speed is not increased;

· the overall width of the level crossing remains the same;

· level crossing closure times may be reduced as train working may occur in parallel.

Track and Civil

· New suburban track and New High Speed track;

· 2 New 100kph crossovers and 2 new 65kph crossovers;

· Aviation Station significantly reconstructed;

· Laverton station unchanged;

· Goods siding converted to High Speed Track;

· Section of SG track moved;

· No additional width required at Aviation Road;

· new bridge over Merton Street;

· Suburban track to be cut into approach span of Princes Highway Bridge.

Signalling

· Install a new interlocking to control Laverton and the junction;

· Install all new line side signals

Time benefits

The major benefit of these works is the improved flexibility in the timetabling and train operations in this area as a number of opposing moves are removed from impacting upon the operation of the Geelong line trains. No detailed time has been quantified for this but this is expected to be of the order of one to two minutes savings. Greater savings may be realised in the event of out of course train running (ie when the train is already late).

Cost Estimate

Comparative Cost (excluding design management and contingency)

Track and Civil/Electrical $ 10.5 Million

Signalling $ 7.5 Million
