6.1.4 Implications for the rail network<br />

<strong>Final</strong> <strong>Stage</strong> 1 Feasibility <strong>Report</strong><br />

A <strong>Rowville</strong> rail line concept<br />

In the Draft <strong>Stage</strong> 1 <strong>Report</strong> we stated that frequent train services to <strong>Rowville</strong> could not be<br />

provided before improvement works are carried out to the Dandenong Line between<br />

Huntingdale and Caulfield, and also until the Melbourne Metro <strong>Rail</strong> Tunnel is built to provide<br />

more rail capacity through central Melbourne. This section provides more information about<br />

these issues, prepared in consultation with Public Transport Victoria.<br />

Dandenong rail line<br />

The Dandenong rail line currently carries 18 trains in the busiest hour (16 Metro and 2<br />

V/Line), inbound in the morning weekday peak. This level of service is close to the current<br />

capacity of the line which is limited by a number of factors, including:<br />

timetable coordination with Frankston line services;<br />

timing, running times and inner area routing of V/line services;<br />

the rolling stock available to run train services simultaneously;<br />

the minimum time between trains that the signalling system can handle;<br />

the capacity of the electrical power supply; and<br />

road traffic congestion at level crossings.<br />

Addressing the most immediate power supply and rolling stock constraints would only<br />

provide sufficient capacity for next 3-5 years. Beyond these short term measures, a<br />

submission has been made to Infrastructure Australia for further capacity increases requiring<br />

major investment, including:<br />

grade separations to avoid worsening and unacceptable road congestion;<br />

further power supply upgrades;<br />

higher capacity signalling to enable trains to run closer together safely; and<br />

longer trains with increased passenger capacity.<br />

Together these improvements would deliver more than double the present passenger<br />

capacity on the Dandenong line, sufficient up to at least 2030 (depending on the rate of<br />

demand growth).<br />

The Melbourne Metro <strong>Rail</strong> Tunnel<br />

The City Loop can only accommodate current six-car train lengths due to the length of the<br />

underground station platforms, which cannot be easily extended. It would not therefore be<br />

possible to operate Dandenong rail line services through the City Loop if they used longer<br />

trains. It is also very difficult to extend Richmond station for longer trains without a major<br />

rebuild (planning for the Richmond Station precinct is continuing to investigate provision for<br />

future extension and widening of platforms).<br />
