The routes are 62: North Walbottle-Killingworth Bus Station, this interworks with 63:
Chapel-House-Killingworth Bus Station
The X63 doesn't serve any of the above locations, it goes from Monument to Killingworth West Bailey not calling at Killingworth Bus Station, it runs anti-clockwise round Killingworth
Out of the 4 X63s 3 of them run onto 62/63.
18:30 63
18:42 62
19:12 62
The last x63 is the only one that doesn't run onto a 62/63
