yep the 231 Newcastle-Chester-Le-Street-Fence Houses-Houghton-Easington Lane-Peterlee-Hartlepool
and the 735 Newcastle-Chester-Le-Street-Fence Houses-Houghton, both providing a 30 minute service. 735 used to go through Houghton to Seaham but wasn't profitable for Northern, so the Houghton to Seaham had to be secured with a 148 service.
