Thought of this the other day when I was standing at the bus stop after arriving a few minutes late for a bus. The Transport Dept does not list the bus stop on the online or paper timetables so I decided to take a photo of the timetable on the sign at the bus stop with my phone so that I have a readily accessible timetable for my local bus stop on hand.
This is a trick I've used myself. Even if your online timetable does include every stop, pulling up a single file is quicker than navigating through a site, and having it on your phone makes it portable and accessible even if you're in an area with dodgy signal. Thanks Xponti!
