Mills Hill lies on Middleton's common boundary with Chadderton,[1] and thus serves both communities.

It is due to this fact that TfGM are pushing for funding to be made available to improve accessibility at the station for disabled passengers.

Since the May 2018 timetable change, the service pattern here has been completely revamped (though the half-hourly basic frequency remains unaltered).

All trains (apart from a small number of weekday peak and late evening workings) run to/from Rochdale only, with passengers for destinations further north having to change there.

[3] On Sundays, an hourly service operates with trains running to Southport via Wigan Wallgate southbound and to Blackburn via Todmorden and Burnley Manchester Road northbound.
