A 200 km long railway line was built by the Compañía Minera de Sierra Menera S. A. in 1903 in order to bring the iron ore to the harbor of Sagunto. This was the longest private company-owned railway line in Europe. A blast furnace facility also belonging to the company was also located in Sagunto, where a pelletizing plant and a long jetty were built in the 1970s.
