Blea Moor Tunnel

Blea Moor Tunnel is a 2,629 yd (2,404 m) railway tunnel located between Ribblehead Viaduct and Dent railway station in England. It is the longest tunnel on the Settle-Carlisle Line, being almost twice as long as the second longest tunnel, Rise Hill Tunnel.
History.
Built by the Midland Railway, it took more than four years to complete. Construction started in 1872, with dynamite transported from Carlisle and Newcastle in carts to the construction site. The wages on offer to the miners who dug the tunnel were 5s () to 5s 6d () per day.
It was completed in 1875 at a cost of £109,000 ().
It passes some 500 feet below the moor after which it was named, and was built with the aid of seven separate construction shafts sunk from the moor above. This permitted sixteen separate gangs of workers to be used during construction (one from each open end and two from the foot of each of the shafts). Four of these were subsequently filled in but three were retained for ventilation purposes and are still used as such today (with occasional ice accumulation problems: ). At one point of the track's history, steam locomotives were tested for their worthiness by driving them through this tunnel.
Traffic.
Any train that goes the full length of the Settle & Carlisle line goes through the Blea Moor Tunnel. This includes passenger trains, all run by Northern (seven each way per day in the 2016-17 timetable), various special excursions (some hauled by steam locomotives) and the many goods trains.
