Now, as the 2 are combined to give a 15 minutely Peterlee-Hartlepool, this doesn't happen, nor does the 23 interwork with the 24. As such, driver changeovers happen in Sunderland using staff cars from Durham.
Extending the 23 to Middlesbrough would then allow the operation to pass to Stockton and enable drivers to change there (although, depending what route they took from Hartlepool to Middlesbrough would then depend on driving hours).
Oh right, well It'd be good for that, and for new links.
