No scheduled weekend double deckers on the X31, but there are a small number during the week:
- 07:38 STY - NCL, 11:45 NCL - STY, 12:30 STY - NCL (bus operates PM 808)
- 19:05 NCL - STY (runs off X70/X71)

Yes it is the xx:30 47s from Newcastle (xx:28 from Blackhall Mill) that are the Toon Links, but the following are scheduled for Red Kite B9TLs (as far as I am aware):
- 10:56 BHM - NCL, 15:00 NCL - BHM, 15:58 BHM - NCL, 17:00 NCL - BHM, 17:55 BHM - NCL, 18:50 NCL - BHM
