It done the 0720 57 from Durham to Kelloe, and then ended up being the 1640 57 Durham to Kelloe. 

Not entirely sure how the interworking works, but I assumed it to be something like this:

0720 Durham - Kelloe 0751 - 57

0751 Kelloe - Durham 0829 - 57
0840 Durham - Bishop 0943 - 56
0950 Bishop - Durham 1054 - 56
1100 Durham - Hartlepool 1200 - 57A
1202 Hartlepool - Durham 1304 - 57A
1310 Durham - Bishop 1413 - 56
1420 Bishop - Durham 1524 - 56
1535 Durham - Kelloe 1606 - 57
1606 Kelloe - Durham 1639 - 57
1650 Bishop - Durham 1753 - 56
1800 Bishop - Durham 1904 - 56

Obviously wrong though
