The Bridgnorth Castle Hill Railway Company Ltd was registered in 1891, and construction started on 2 November 1891. The railway was opened on 7 July 1892 by Mayor William Burton.Originally the railway was powered by a simple system using water and gravity. Water was pumped into a 2,000-imperial-gallon (9,100 l; 2,400 US gal) tank beneath the top car until its weight, a maximum of 11.5 long tons (11.7 tonnes), overcame that of the lower car. When the car reached the bottom station the tank was emptied and pumped up to a 30,000-imperial-gallon (140,000 l; 36,000 US gal) tank on the top of the upper station.
