San Cosme. By 1871, the aqueduct was no longer used and crumbling and the city decided to sell the lands. Part of it was purchased by the Ferrocarril Mexicano, which opened Buenavista Street to provide better access to the nearby train terminal. This terminal began operations in 1873, and son became known as the Buenavista station. This terminal reached its height at the very beginning of the 20th century. The station and the rail system in general waned as a nationwide highway system developed in the 20th century. The station was closed in 1958, in order to build a newer station nearby. The old station was demolished and the lands it was on began to be urbanized, extending Buenavista Street north to Avenida Central and adding new streets such as Aldama and Violeta. The offices of the Cuauhtemoc borough were constructed here in the 1970s. In the 1990s, the Ferrocarriles Nacionales was sold into private hands and operations in Buenavista ceased in September 1999. The Buenavista train station closed and only some cargo freight currently passes through the area. It was replaced by the Buenavista station of the Tren Suburbano which became operational in 2008. It and the library have spurred much change in the colonia. While some of it has been positive, such as investment in new and existing businesses, some negative such as walled off areas that have attracted crime. The goal of the development projects have been to revitalize the area which had deteriorated badly since the closing of the rail yards in the 20th century. References Buenavista
