A test site for high-capacity signalling is now being established at the Pakenham East Depot in Melbourne.
The test site will allow for the introduction of high-capacity signalling, described as “moving block” signalling systems, instead of “fixed block” systems. The new signalling system will enable trains to automatically adjust their speed, in order to maintain a safe distance from the train in front. This technology differs from current systems, which tell trains when it is safe to proceed to a new section of track via coloured signals.
High-capacity signalling is delivered by the Rail Systems Alliance, a consortium of CPB Contractors, Bombardier, Metro Trains Melbourne, and Rail Projects Victoria.
The test site will be constructed at Nar Nar Goon, in south east Melbourne. This will enable access to the high-capacity signalling platform and test track, situated inside the Pakenham East Depot.
Trackside equipment will be installed between March 2 and 6.
On the Melbourne network, high-capacity signalling will be installed on the Sunbury to Cranbourne/Pakenham line, as well as the Mernda Line between Epping and South Morang.
Signal control centres will be built at Sunshine and Dandenong. Signallers will support train movements across the lines from here, including through the Metro Tunnel.
In addition to the high-capacity signalling work, new high-capacity metro trains will be introduced on the Melbourne Metro network. On the platforms, floor-to-ceiling platform screen doors will be installed. These will reduce overcrowding, dwell times, and improve tunnel ventilation. These will be designed and supplied by Faiveley Transport. The platforms screen doors will also be tested at the Pakenham East depot.
