B.R. Standard class 4 2-6-0 76084 near Sheringham with 1M10 10.33 Sheringham - Holt service North Norfolk Railway 2nd September 2017.

The North Norfolk Railway (NNR) – also known as the "Poppy Line" – is a heritage steam railway in Norfolk, England, running between the coastal town of Sheringham and Holt. It cuts through the countryside to the east of Weybourne with views of its windmill and passes through the well preserved country station which also houses a locomotive shed together with a carriage maintenance and restoration centre. The Norfolk Orbital Railway, an independent organisation, has plans to join and link the NNR with the Mid-Norfolk Railway.
The line, which is just over 5 miles (8.0 km) long, once formed part of the Midland and Great Northern Joint Railway. Work on rebuilding the line started in 1965, and on 4 June 1967, two steam locomotives were delivered. The operating company, North Norfolk Railway plc, was launched in 1965 following the granting of two Light Railway Orders. In May 1973, the railway was the scene of filming for the episode "The Royal Train" of the popular TV programme Dad's Army. The railway won the 'Independent Railway of the Year' award in 2006.

At Sheringham the line has now been reconnected to the National Rail network station via an 'occasional use' level crossing. There are two stops between Sheringham and Holt – Weybourne (about 1 mile (1.6 km) from the village) and Kelling Heath.

The main restoration sheds are at Weybourne. They have room to accommodate four standard length British Railways Mark 1 coaches and six large steam or diesel locomotives. New carriage storage sheds have been built near Holt with Heritage Lottery funding. These have the capacity to store the equivalent of 18 Mark 1 coaches. The railway is operated mainly by volunteers. There is also a Junior club for members who are aged between 10 and 15. Every year there is a volunteer of the year award and also the 'John D Hammer' trophy for the 'Junior volunteer of the year'.
The NNR operates both steam- and diesel-hauled services, and organises a programme of seasonal special events including two steam galas, a diesel gala, Santas, "Day Out With Thomas" and an annual beer festival. A museum has been built at Holt to display artifacts from the Midland and Great Northern Joint Railway. The station building at Holt was originally built at Stalham in 1883 and was moved, brick by brick in 2002, to be re-erected in its current location. This project was awarded second place in the 2006 railway buildings competition by the Heritage Railway Association of the UK. The signal box at the station is over 100 years old and was restored on-site. The full signalling system at Holt, with 14 signals as well as the box, was commissioned in 2009 – winning the HRA signalling award for that year. The box was formerly at Upper Portland Sidings in the East Midlands.
There are several improvements planned for the railway. Now that the level crossing at Sheringham has been reinstated, one of the next projects is to rebuild the demolished buildings on Platform 2 at Sheringham station. The stanchions for the project are at Weybourne. This is seen as a medium to long term project, but a start may be made soon on erecting the stanchions. The project would also see a footbridge replaced to complete the original station look. The Tourist information Centre and public toilets that sat on the footprint of part of the trackbed between the station and the network rail link have been demolished and rebuilt in the style of the station, releasing the old trackbed alignment for future development.

Holt station is also being developed; its progress has been rapid over the last few years. Projects include installing the weighbridge from Cambridge station, putting up a footbridge, and reconstructing a 'carriage house' (completed late 2009), a relocated example of the houses made with old railway carriages in the war years.
