Not in the station, but very close

The eastern portion of this line was retained for freight traffic after passenger trains ceased (serving the coal depot at Rawtenstall until 1980 and subsequently to the Powell Duffryn wagon works) 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 (named Castleton Village) 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 Moucel in conjunction with the ELR regarding the proposals in 2010 - their report (which covers both the tourism & regeneration aspects of any such future development) can be downloaded from the ELR website.
