So there was indeed a more frequent service than there is currently across the day, although the peak service now (Regent Centre/Monkseaton to Pelaw) is more or less the same. Also, the frequency on the yellow and green lines was every 10 minutes during the day, as opposed to every 12 minutes as it is currently.
Ah that's fair always thought they were just peak extra lines, knew they were every 10 minutes though which I believe they're wanting to do again.
