The loop is intended to be controlled by a signal box built using components from the box from East Winch railway station on the Dereham to King's Lynn line, and includes provision for an eventual restoration of a section of double track railway south of the station potentially to Kimberley Park. The McKenzie and Holland lever frame recovered from Seven Sisters signal box was installed in the signal box at Thuxton in August 2014 with plans to commission it during 2015.
