If you did put on an express service to the coast you would be competing with a Metro service running every 12 mins. CLS has service 50 every 30 mins to Shields taking an hour. Connections are available to Whitley Bay and Tynemouth via Newcastle and they also have a direct service to Sunderland. I don't see a market for them.
There may be a market for a service from Newcastle/Sunderland to Whitby and Scarborough in the summer months, something Arriva have sadly neglected!
