After I posted yesterday about the 530 Driffield Town Service being reduced from Monday to Friday to Tuesday and Thursday only operation in October, a comment left brings good news - a Friday service will be restored from January 6th. More details here.
The 530 is operated by Holderness Area Rural Transport (HART) for Driffield Town Council and East Riding of Yorkshire Council.
Additionally I should note that it appears bustimes.org is not showing the complete service 530 timetable, and that the final 1418 afternoon journey is still running. Again thanks to this comment for pointing this out.
