The aim of the society was to reopen most of the former Midland Railway branch line from Wellingborough to Higham Ferrers, which had been closed completely in November 1969.

As of April 2016, around 1⁄2 mile (0.8 km) stretch of the line is operated between Rushden station and Prospect Avenue.

They are unable to extend back towards Wellingborough due to developments that have taken place along the route of the old branch line.

The most recent station cats, Alfie and Thomas, have achieved minor fame on social media.
