Wansford Tunnel

Wansford Tunnel is a railway tunnel on the preserved Nene Valley Railway in Cambridgeshire. The tunnel is situated to the south of the village of Wansford, but just to the west of Wansford railway station.

It was on the Blisworth to Peterborough line opened in 1845 by the London and Birmingham Railway. The line originally was double track. Today, however only a single track runs for its full length, the other track being used only as a siding. The tunnel is 616 yards long (but has no ventilation shafts) making this the fourth longest tunnel on a UK Heritage Railway.

Just to the west of the tunnel the NVR has opened a new station, Yarwell Junction railway station, which opened to the public in 2007.

The hamlet of Sibson is on top of the tunnel.
