A consortium of CPB Contractors and Bombardier Transportation will deliver the $1 billion Rail Systems Alliance package of works, which includes the first roll-out of a high capacity signalling and communications system on an existing rail network anywhere in Australia.
As part of the Metro Tunnel project, 55 kilometres of next-generation, high-capacity signalling (HCS) will be installed. HCS allows trains to safely run closer together, meaning they can run more often.
The advanced technology will enable trains every two to three minutes – creating a true 'turn-up-and-go' train network for Melbourne.
The signalling will operate the 65 new high-capacity trains which will run on the Sunbury to Cranbourne-Pakenham line via the Metro Tunnel.
Dedicated control centres will be built in Dandenong and Sunshine to support the new technology. The centres will be staffed by experts who will monitor trains on the new Metro Tunnel line.
