Wonderful. This is the sort of stuff I love to read about.
Tfl in the UK use a similar system AFAIK so it's almost worth considering doing the same here.
Nice touch that a tilde appears when the timetable time is shown instead of live data. They should introduce that here.
They used to show a "clock symbol", which is still present in the LCD screen. But I suggested them using tilde sign, when those were in beta. I never was quite sure if the clock did mean accurate real time information or time table based information. I assume it did mean time table based info.
