I rode the Southern Cross Citylink route from Ipswich to Indooroopilly one morning, in December 2008 IIRC. It was the first service of the morning (I can't be bothered rummaging through my TT collection right now to find the correct time, I think it left Ipswich Transit Centre about 7:30am). There was only one passenger besides me (a blue-collar shiftworker who got on at Ipswich and got off at Karalee). I was surprised there were no commuters or Indro shoppers catching the service.
While at Ipswich, the driver received a message on the radio to wait for the other passenger, who had called the depot on his mobile from a late-running train, which I thought was a nice old-style touch. The driver practically begged me to sign a petition asking the government to fund the service and handed me some literature to take home.
I agree that it's probably not economically feasible for Citylink to be funded by the state, which raises the question - why are the 282, 399, 540 and other peri-urban routes included in the TL network?
