Built of blue engineering brick with stone portals, Gomersal's 819-yard tunnel was cut in 1899 as part of the Leeds 'new line'. On the surface, above its centre, is the Shoulder of Mutton pub which was bought by the LNWR during construction, in case it fell into the workings. Now, when draymen use the barrel drop, the noise echoes around the tunnel and vibrations are felt in the cottage next door. The odd brick structure at the western end would have allowed access for inspections after the approach cutting was infilled. But, at the last moment, Railtrack and Kirklees Council dithered and, in 1997, decided to stop any further tipping on the site.
