A bit late... but still:
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
