Living in Queensland Australia I have a GoCard. It covers trains buses and ferries: if you go on a journey that uses some or all of them, it is treated as one journey, half price of course, 'cos I'm over 65. There are three kinds of GoCards" blue for full fare, ie workers, green for concessions, ie people on benefits, and red for oldies.
I use it all the time: it costs me A$ 1.53 to go to our nearest city, Ipswich, one way. It is about 8 kilometers.
I love our local electric commuter trains; they run on time, are airconditioned and safe. I have an 8 minute walk to the station, where I have a natter to the station master and other locals, then a 10 minute journey, then I have an easy 5 minute walk to the library, where our U3A writers' Group meets. it is all very relaxed and easy, compared with the parking problems drivers get.
