Kilsby Tunnel Chimneys

The Kilsby Tunnel is a railway tunnel that was developed on the West Coast Main Line in England, near the village of Kilsby in Northamptonshire. Construction started in May of 1835. Located roughly 5 miles (8 km) southeast of Rugby. It is 2,423 yards (2,216 m) long.
The tunnel had atypically large ventilation shafts, because of a lack of experience as to how much ventilation would be needed for steam locomotives to pass through.
In May 1836, work started on the first of two shafts, which were 132 feet deep and 20 yards in diameter. The shafts were sunk using sequentially dug trenches around the circumference and took over a year to reach the bottom of each shaft.
Its three-foot-thick walls required over one million bricks and weighed an estimated 4,034 tonnes. For aesthetic reasons both shafts are castellated
On opening in 1838, the tunnel was single track and in 1879, double-track was laid. In March 1987, Kilsby Tunnel portals and its two ventilation shafts were given listed status.

Yes mate, thats the one, just off the A5. Thanks mate. Was a tough one, there's a bloody 5g mast across the road, signal kept dropping due to interference. RTH was initiated three times, then it started raining haha!
