Queensland Rail said yesterday that it expected to select a vendor in August to roll-out Wi-Fi services on its suburban Citytrain network, with trials of the technology to start in October.
"We have received substantial interest from companies working in this field; 29 submitted proposals which were highly detailed and technically complex," Transport Minister Rachel Nolan said in a statement.
Three suppliers have already been shortlisted: Dimension Data, Wellard Technologies and Fujitsu.
"By July we will be asking these companies to submit an offer which will allow us to properly compare the proposals; from there one company will be selected to roll-out the trial," she said.
The wireless internet service will provide coverage to commuters and allow streaming of on-board CCTV cameras. However, getting the network up and streaming CCTV images are the priority, with Wi-Fi coverage to be tackled afterwards.
