On the track bed of the old potteries loop line (of the North Staffordshire Railway). This tunnel is near Burslem in Stoke-on-Trent. The railway ran under a road and then carries on towards Tunstall I think. This footpath runs between a few of the six towns of the potteries. Maybe it could be used as a light transport system avoiding clogged roads. If it was I’d hope it also allowed pedestrian and cycle access. This green pathway allows walkers to breathe cleaner air than alongside the road system.
