The city became the main hub of the national railway system. The first railroad reached the city on 14 September 1857, at the Santiago Estación Central railway station. Under construction at the time, the station would be opened permanently in 1884. During those years, railways connected the city to Valparaíso as well as regions in the north and south of Chile. The streets of Santiago were paved and by 1875 there were 1,107 railway cars in the city, while 45,000 people used tram services on a daily basis.
