The tunnel was designed and built by George Stevenson and was opened in 1859 as a single track line from Market Harborough to Northampton. Later when the line was double tracked another tunnel was bored next to it.
The open (to the public as a footpath/cycle way) tunnel is 453 yards long with just one air vent.
The other tunnel is 462 yards long.
