Preservation efforts began in 1974, but the line re-opened to passengers only in the mid-1990s as part of the "New Generation" of heritage railways.
  Regular steam and diesel services run 11 1⁄2 miles (18.5 km) through the centre of Norfolk between the market towns of Wymondham and Dereham via Yaxham, Thuxton and Kimberley Park, and occasional sightseer services continue north of Dereham passing the nearby village of Hoe, where there is no station, to the limit of the operational line at Worthing. The line is periodically used for commercial freight operations and staff instruction for mainline railway companies.

The MNR own and operate the majority of the former Wymondham-Fakenham branch line of the Norfolk Railway. The branch opened in 1847, was closed to passengers in stages from 1964 to 1969 as part of the Beeching cuts, and was finally fully closed to goods traffic in 1989. (The northern section of this line, to Wells, was built by the Wells and Fakenham Railway and part of this has been operated by the Wells and Walsingham Light Railway since 1982.)

The MNR is owned and operated by the Mid-Norfolk Railway Preservation Trust (MNRPT, a charitable company limited by guarantee, and is mostly operated and staffed by volunteers. The company owns a further 3 1⁄2 miles (5.6 km) of line, as far as County School railway station, which will make it the third longest heritage railway in England once restoration is complete. The Mid-Norfolk Railway has had a long-term, published ambition to restore the railway as far as Fakenham.
