(07 Dec 2020, 10:33 pm)Jimmi wrote X21 was revised to serve all stops between West Auckland and Chester-le-Street, Front Street when the frequencies on the Durham to Chester stretch on the 21/X21 were revised around the start of the year (X21 since reverted to half hourly for the whole route)
Sorted then.
Send the 21 via Waldridge Park, continue the X21 as is. Have the 50 fill any gaps left between Clifford Terrace and the Arnison Centre.
Opens up the 21 to more residential areas (therefore increasing its footprint and scope to attract passengers on a frequent service) and hopefully it helps take away some of the traffic from the Arnison Centre.
