Thackley Tunnel is on the Airedale line between Leeds and Shipley on the lines to Bradford and Skipton. Completed in 1846 and opened on 30 June, the tunnel is approximately 1,300 yards (1,200 m) long through Thackley Hill. The contractor was James Bray, an iron and brass founder from Leeds who later contracted the construction of the Bramhope Tunnel on the Leeds to Thirsk main line.
