, here's a basic tour of some of the interesting things you can find in TripView
Once you create your trip, say, Central > Redfern
, you get to this screen. Tap the context menu button, then tap "View style" to view what you described as the "PID looking thing".
When you press the "GPS/target" button (for lack of a better word), it brings you to a nice map of the network with the real-time locations of the trains on the route you selected, not unlike the TLS system (which is only accessible from RailCorp computers, by the way).
Tap the bottom bar (highlighted in the second image below) FIVE times quickly, then tap on one of the train targets, and much more information is revealed, such as the consist and run number.
Hope this helps!
