The Great Central Railway (Nottingham) is a heritage railway and Transport Museum on the south side of the village of Ruddington in Nottinghamshire. The route consists of almost 10 miles  of the former Great Central Railway Main Line from Loughborough South Junction (with the Midland Main Line) to the site of Ruddington's former GCR station site, plus a branch line  to the Ruddington Fields site located on a former Ministry of Defence site next to Rushcliffe Country Park.                                                                                                    

There are stations open to the public at Ruddington Fields (within the main centre site) and at Rushcliffe Halt & the GCR(N) aim to re-open the former station at East Leake in the longer term                                                                                                                                    

The railway is currently not connected to Great Central Railway (at Loughborough Central in Leicestershire), although there are plans well underway and work has started to reunite the two preserved lines. This is a major engineering project that is expected to be completed during 2024 - 2028. Some 5.5 miles (8.9 km) of the line is used by gypsum trains serving the British Gypsum works at East Leake.
