Brighton and Rottingdean Seashore Electric Railway

Former railway in England

The Brighton and Rottingdean Seashore Electric Railway was a unique coastline railway in Brighton, England, that ran through the shallow coastal waters of the English Channel between 1896 and 1901. It was designed by Magnus Volk to extend his Volk's Electric Railway from its terminus in Paston Place to the village of Rottingdean and avoid difficult terrain. While the unique railway was popular and carried tens of thousands of passengers, it was ultimately abandoned to make room for new sea defences, and Volk was unable to raise the funds to construct a replacement.

Magnus Volk, its owner, designer and engineer, had already been successful with the more conventional Volk's Electric Railway, which had then not been extended east of Paston Place. With unfavourable geography in that area, Volk decided to construct a line through the surf from a pier at Paston Place to one at Rottingdean. This was also home to Volk's Seaplane Station which was used by his son George Herbert Volk. The railway itself consisted of two parallel 2ft8.5in gauge tracks, billed as gauge, the measurement between the outermost rails. The tracks were laid on concrete sleepers mortised into the bedrock. The single car used on the railway was a pier like building which stood on four 23 feet (7 m) long legs. The car weighed and was propelled by two vertically mounted General Electric electric motors operating through shafts to worm drives on two of the four bogies. Rod operated brakes were fitted to the other two bogies. The controls were on the upper promenade deck (the railed enclosure surrounding the skylight of the passenger saloon). Although originally intended to be powered by accumulators, electricity was supplied by two overhead lines suspended alongside the tracks; initially only one wire had been used, with an earth return through the rails (or the sea itself at high tide). The power station, beneath the pier at Rottingdean, was equipped with a steam engine from William Sissons and Co. of Gloucester driving a 50 kW dynamo at 500 volts. It was officially named Pioneer, but many called it Daddy Long Legs. Due to regulations then in place, a qualified sea captain was on board at all times, and the car was provided with lifeboats and other safety measures. Construction took two years from 1894 to 1896. The railway officially opened on 28 November 1896, but was nearly destroyed by a storm the night of 4 December. Volk immediately began rebuilding the railway, including the Pioneer, which had been knocked on its side. Pioneer was salvaged and brought ashore, and rebuilt with the legs two feet higher than the previous design. After repairs to Pioneer and the railway were complete, service resumed on 20 July 1897. Eventually Volk's Electric Railway was extended onshore, covering a portion of the same distance; it remains in operation. A model of the railway car is on display (along with a poster for the railway) in the foyer of the Brighton Toy and Model Museum.

St. Malo, France, between 1873 and 1923 had a single track railway across the harbour, running on submerged rails, bearing a strong resemblance to Volk's Pioneer. The vehicle was cable hauled rather than self propelled, however. Some ferries are arranged to operate on underwater rails; for example, some diesel powered ferries across the Amsterdam Rhine Canal in The Netherlands. Several theme park attractions, including the Mark Twain Riverboat at Disneyland, feature vehicles guided by submerged rails or guideways.
