I might as well list the movements now then shouldn't I:

39702-5 South Shields-Slatyford, replacing 35159-62 to Hartlepool
39706-9 South Shields-Sunderland, replacing 35155-8 to Hartlepool
39710-4 South Shields-Hartlepool

As yet, nothing is confirmed as to what 35155-62 and 39710-4 replace at Hartlepool as there's only 13 buses transferring in yet there's 15 Pointer Darts at Hartlepool (not including 34401 in reserve)
