20, 56, 60 were all dropped from every 10 minutes to every 12 to improve reliability.

In all fairness, the 20/60/56 can all manage to be put back to every 10 mins, and 56 to every 12 considering 60 has atleast 5 mins layover at Sunderland, 56 has like a 15, and 20 going to South Sheilds/DUrham from Sunderland atleast have 5 mins.
