Linespeeds were raised last year between Rochdale and Newton Heath to 90mph (into Manchester) and 80mph (towards Rochdale) .So am I right in thinking that under the Dec 2019 timetable you describe, Rochdale to Victoria will have 7tph, assuming all will stop. If so, quite a healthy frequency for that route. Definitely helps the case for future wires if so, and I imagine ridership will increase a lot - especially if at that frequency, fast journeys can be made possible. When is the last time signalling or line speed improvements were made?
