Concrete sleeper - Wikipedia
In 1877, Joseph Monier, a French gardener, suggested that concrete reinforced with steel could be used for making sleepers for railway track. Monier designed a sleeper and obtained a patent for it, but it was not successful. Concrete sleepers were first used on the Alford and Sutton Tramway in 1884. Their first use on a main line railway was by the Reading Company in America in 1896, as recorded by AREA Proc
