As has become the norm, the upcoming strike timetables reveal north west Northern can only manage an hourly Manchester Airport to Liverpool service.
Meanwhile, eastern Northern can manage an hourly service on most commuter lines around Leeds, and Saltburn to Bishop Auckland.
No one has been able to provide an adequate response as to why Northern cannot manage an hourly service on well patronised routes including Bolton - Oxford Rd or Preston - Blackpool North. The former would require only 2 trained managers as stand-in guards, plus a dispatcher at Bolton. Omit Salford Crescent if it's problematic to resource. Deansgate is self-dispatch and Oxford Rd must already be staffed for the Liverpool service.
