Visit every CityTrain station.... in just one day

[HappyTrainGuy]

Anyone here up for a little challenge or maybe just a fun day out? How about visiting every single in revenue station on the CityTrain network in just one day by train only. Start at Central and finish at Central. Can it be done? Should it be done? Would it be done? Over 700km and 140 odd stations

It should be possible to do. Roughly 21h30m to cover all routes Central-Terminus-Central + interchange/waiting time. Doubling up on routes should reduce the time to just fit in with their operating hours (Gympie North exp Central-Gympie North, Roma Street exp Gympie North-Caboolture, Ipswich all stations Caboolture-Central etc.)
