However, you'd need 2 buses for the 35 with a layover in Newbiggin of 39 minutes. So, from logical reasons, the interworking remains in place.
There's also the fact that Ashington's entire Sunday output is either Sapphire on X21/35 and X22 or MAX on the X15/X18/418.
Leading on from this point, do you think the X20/20 will start to operate on Sundays when it goes MAX?
