The extremely steep ascent of a narrow gauge tramway left behind in the Cheshire hills. Once used around 80 years ago during the construction of Bulkeley reservoir, a haulage engine lifted locomotives up and down this 45 degree incline which would've been the only way to obtain the required materials at the top of the hill. The line was abandoned after its purpose was served, but the newly connected gravity-fed water main was successful in distributing water to the potteries as far away as Staffordshire.
