Sydney’s public transport has a few burdens, including trains that rarely arrive on time and zero mobile coverage through some of the tunnels. While we can’t quite help with that first one, Optus has teamed up with the NSW government and RailCorp to fix that second one.

Launched this week, phones of commuters travelling through the North Shore and Western Line tunnels will now receive signal, allowing passengers to keep chatting on the phone, browsing the web, and texting their friends and family.

“Today marks an important step in delivering much-needed rail tunnel coverage to Sydneysiders as they travel around this beautiful city,” said Günther Ottendorfer, Managing Director of Optus Networks.

“Sydney customers have been waiting far too long to use this service and it is a testament to the Minister for Transport, the Hon. Gladys Berejiklian MP, that we are able to make this announcement today, who accelerated this project by making it a top priority.”

The good news is that the improvements to the train network and how it works with smartphones won’t stop there, with the project eventually rolling out to tunnels in Sydney’s City Circle, eventually aiming to introduce strong 3G signals to the rest of Sydney later this year.
