Kilsby Tunnel

The tunnel is located near the village of Kilsby in Northamptonshire roughly 5 miles (8 km) southeast of Rugby. The tunnel is 2,432 yards (2,223 metres) long.

The tunnel was opened in 1838 as a part of the London and Birmingham Railway. At the time of it's opening, Kilsby tunnel was the longest tunnel in the world, and is today the 18th longest tunnel on the British railway system.

The tunnel took far longer, and cost far more money to build than had been anticipated. This was because the tunnel builders encountered unexpected quicksand[?] which trial borings into the hill had not revealed.

It took three years, and cost £320,000 to build (three times the original estimate).
