To be fair, I doubt the hour sat outside Church Fenton could have been anticipated.Thursday at Scarborough: 0835 arrival 21 minutes late, 0846 departure therefore 15 late and terminated at Huddersfield 78 late.
The 1535 arrival into Scarborough / 1546 departure has been cancelled AGAIN.
So it has been cancelled on Monday, Tuesday and Friday this week.
The 1535/1546 must be a prime candidate for turning short because of the Leeds evening peak. In which case, it should also be a prime candidate for a planned alternative at least on Fridays - as yorkguy's report on loading flags up.
