Improved mobile phone coverage in train tunnels

Posted: Monday 16 July 2012

Customers on their mobile phonesCityRail customers will now be able to stay connected with friends, family or work in train tunnels on the North Shore and Western Line after mobile phone 'blackspots' were eliminated between Central Station and Chatswood today.

Customers have cited the lack of connectivity as a key frustration on their journeys, and this initiative means customers will be able to enjoy mobile phone and data coverage uninterrupted.

Customers using the Optus and Telstra mobile networks will be able to enjoy the new coverage immediately, with work to connect Vodafone's network expected to be completed in the near future.

Almost 10km of special cables were laid on tunnel walls in the CBD, North Sydney and Chatswood to enable this enhancement. Extensive design and testing work was required to ensure that the new cables didn't infringe train communications and signalling systems. This type of work is just one example of activities undertaken during trackwork.

The new mobile coverage is part of an overall program to improve communications on the CityRail network.

Plans are underway to roll out further mobile coverage infrastructure at other mobile blackspots on the CityRail network, with preliminary scoping and design works planned for tunnels along the City Circle and Eastern Suburbs Line.
