(20 Dec 2019, 1:06 am)peter wrote The overall PVR at Durham looks as though it will be going up by 3 due to the extension of the 57, rerouting of the 57A and the 56/86 no longer interworking with them. If my calculations are correct, from January there'll be 6 buses on the 56/86 and 6 buses on the 57/57a circuits compared to 9 across them all currently. However, from the same date the PVR at Blyth looks to be going down by 1 thanks to the X7/8 starting to interwork with the X9, so an overall increase of 2.

56/86 and 57/57A have been separate since the October service changes - with layover time in Durham between trips.
