In November 2012 planning permission was granted for a new track extension, enabling the long term plan always envisaged by the society to be realised. Work started in the first quarter of 2013 for the 650m long extension through the muddy field towards the Richard Jefferies museum, with over 600 tons of hardcore being used to build up the embankments.
 
In November 2015 the concrete and track had been finished on the extension, a new platform at Richard Jefferies museum had been laid, and the first trial trains were hauled on the 27th December 2015. The first public trains were hauled on Good Friday 25th March 2016, followed by the official opening of the Richard Jefferies halt by MP Robert Buckland on the 31st July. The extension was officially opened during the 17th September gala by chairman Ken Parker, with several visiting locos in attendance.

During 2018 we completed fully automatic signalling on the extension, and completed a new junction near the club car park to allow the signalman to direct the trains in different ways. In addition we erected three tunnels on the extension and during the next few years, as funds and resources permit, these will be completed by building brick portals and back-filling to make them look like the real thing.
