The original station opened in 1839, at Blue Pits on the western side of the Rochdale-Manchester Road bridge. It was originally called Blue Pits for Heywood. The current station opened on 1 November 1875. The Liverpool and Bury Railway from Bolton used to join the main line at a triangular junction a short distance south of the station. This was at one time a busy passenger and freight route often used by trains avoiding the busy Manchester area, but was closed to passengers on 5 October 1970.
On Monday to Saturday daytimes, there is a half-hourly service in each direction. From 4 June 2018, apart from a handful of peak hour/later evening and Sunday services, the basic pattern is for trains to start at Rochdale then stop at all stations including Castleton to Manchester Victoria, and continue via Salford Central, Salford Crescent, and to Blackburn, with alternate trains continuing to. On Sundays, the service pattern is hourly between Manchester Victoria - Castleton - Rochdale - Todmorden - Burnley - Accrington and Blackburn. Southbound trains continue beyond Victoria to and via Atherton.
Facilities
The station is not staffed, but a ticket machine is available. Shelters and passenger information screens are located on each platform and both have step-free access from the street.
The eastern portion of this line was retained for freight traffic after passenger trains ceased and it now forms the link with the East Lancashire Railway heritage route at Heywood. The heritage line plans to extend its services along and towards a possible new bay platform adjacent to the main station in the future, subject to permission being granted by Network Rail. The bay platform will be adjacent to the main station at Castleton, from where passengers could alight and change station sides directly to Northern Rail services on the national network. Rochdale Council commissioned a study by transport consultants Mouchel in conjunction with the ELR regarding the proposals in 2010; their report which covers the tourism and regeneration aspects of any such future development can be downloaded from the ELR website.
