Any nightbus in North Tyneside should be on the 1/22 corridor and if not that the 306 extended to Whitley Bay.

There's lots of destinations on that route which have a night time economy:
Whitley Bay - Tynemouth - North Shields - Wallsend - Byker - Newcastle

The only reason buses aren't popular on that corridor much during the day is due to the Metro which doesn't run. It runs through some of the most urban corridors in Newcastle.

The N58 failed when people actually went to Whitley Bay as there's nothing in that corridor to note.
