The bog north of Bingley station was a headache to the railway builders. It is recorded in the "Bradford Observer" of 8 March 1847 that "no fewer than 100,000 cubic yards of solid earth and stone have been poured into this insatiable maw of a bog." The bog has also claimed some of Bingley Grammar School's buildings and the sinking may have given rise to an urban legend about a locomotive and wagons having been swallowed up by the bog. No evidence can be found to attest to this.
