Between Middlesbrough & Stockton it will only serve Teesdale Uni, Thornaby Station and the student flats at Chandlers Wharf
Between Sedgefield & Durham it will only stop at Coxhoe Red Lion, Coxhoe Church, Park Hill, Bowburn Cooperage, Bowburn Hare & Greyhound, Bowburn Mary Terrace then non-stop to Houghall College, Science Site, New Inn and then all stops to Durham.
On departure from Durham the only stops will be St Leonards School, County Hall, Aykley Heads, Framwellgate Salutation, Pity Me Front Street then non-stop to Chester-le-Street Black Horse, Front Street and then the same stops as now to Newcastle.
It doesn't appear that the times will change all that much - but obviously some time will be saved by missing out various stops especially on the run into Durham where the 56, 57 and 64 will pick up more of the load (capacity issues?) from the local stops.
Watch out for more improvements coming soon though
