The original tunnel was single-track, and when the line was doubled a second single-track tunnel was built. The "up" line tunnel is 453 yards (414 m) long while the "down" line is 462 yards (422 m). Due to the small bore, the tunnels were known as "the rat-holes" by train drivers.
The former "up" line tunnel at Oxendon is open as part of the Brampton Valley Way, a linear park which runs from Boughton level crossing on the outskirts of Northampton to Little Bowden near Market Harborough, on the former railway trackbed.
