One of which include doing a X1 to Tow Law and then a trip to Barnard Castle

Indeed, there appears to be quite a few odd interworkings across the region

Darlington have
X1/X75 (1 and 5 appear to be entirely standalone outside of peaks)
19s are interworking with the short 7s between the town centre and Harrowgate Hill
9/10/13A/13B

Stockton have just the two odd ones - 8s are interworking with 17/17a and 28/28a are interworking with 29s due to the reduced timetable on both

Durham have 49/49a/57/57a

Jesmond have 43/X16 (X16 running between Morpeth and Kirkhall only)
Ashington have 35/X21/X22 (compared to the normal Sunday of 35/X21 and X22 being on its own)
Blyth have 1/2 interworking

Of course, there's a few odd peak time and early morning workings - Stockton's includes a non-Sapphire allocation to the late 5s normally on the end of a 5A board (although most 5s are non-Sapphire as there's still only 3 Streetlites available for service).
