Looks like the current short 19 will extended to Killingworth and interwork with the 335.
The 350 seems to coordinate with the 351 to provide a service every 30 minutes between Shiremoor and Newcastle, the 350 then takes a faster route to Whitley Bay via Monkseaton Front Street.
The timetables are on Traveline for anyone interested.
