Explored with The Wombat, Infared, Pigdog and Binky 
I have wanted to explore here for ages; after hearing rumors that this site was going to be converted I jumped at the chance of an explore. Was a really fun day and included wire wool spinning (see Wombat's report). Well worth getting muddy for and dusting off the wellies.
Some history borrowed from Wombat:
Built in 1897, and closed in 1966 was on the great central railway from London to Sheffield. The line was the single biggest closure of the Beeching axe, and the most controversial. It was built not because of gradient, but because the rich owner of the Catesby estate didn’t want a railway blighting his landscape.
27 feet wide x 25 feet high, Ventilation is provided by five shafts. Four of these are 10 feet in diameter but the northernmost - 1,250 yards from the entrance - is 15 feet wide to provide greater air flow. Plans to use it as part of HS2 have now been shelved. There are now plans to convert it to an aerodynamic testing facility.
