 During rebuilding, a number of changes were made to infrastructure along the MSJ&AR route.When Metrolink opened, a 12-minute frequency was provided between Altrincham and Piccadilly, enhanced at peak hours by a second 12-minute frequency from Altrincham to Bury via Manchester city centre.Off-peak passenger demand for the new service proved stronger than expected, not least due to the availability of concessionary fares for students and pensioners on Metrolink in common with local bus services.
