Other routes will have lost mileage, too.
Do they consider how many passengers might have been on the lost miles?
That's the mileage Go North East operates on all of its services in the region during a four week period.
Mileage lost as a percentage of the amount of scheduled 'live' miles which should be operated is as low as figures released on the public domain suggests. Go North East reports its lost mileage figures to Go-Ahead, of whom also produce 'group' figures. If there is a recurring issue causing a great deal of lost mileage, Go North East must make arrangements to reduce this lost mileage.
One of the main reasons "Wear Tees Xpress" service X7 was upgraded from Volvo B10BLEs to Mercedes Citaros was due to the amount of breakdowns the service was facing under Volvo B10BLE operation, and upgrading the service has helped stimulate passenger growth due to increased reliability.
Regulation between Gateshead and Newcastle on service 56 has been regularly discussed in the past, hence why I opted to use this service as an example previously.
