If anything, it will be the X21 that will take the hit when Bedlington Station opens, not forgetting customers in Newbiggin who will most like take the X21/35 into Ashington then the train the rest of the way.

X20 on paper could take a hit, I'd probably say more so at the peak times given the fact the train will actually take 37 minutes and not risk getting stuck in traffic. On an unrelated note, could possibly allow the X93/X94 to finally get sorted if the X20 only warrants single decks as a result.

Worst case for the X21/X22, they'll go down to every 30 mins.
