"Study of the chronology of the construction of Medellín's light rail system, based on direct interviews, tracking of press releases, and official documents. Presents innumerable strategic and executional barriers that plagued the project. The author's stated intention is to generate discussion about the role of the State and its institutions in projects such as this one, and to explain lessons learned to avoid committing similar mistakes in the future"--Handbook of Latin American Studies, v. 57.
