English Abstract: The objective of this paper is to study the relationship between the process of urbanization of the southeast of Bogota, the area known as San Cristobal, and the tramcar during the first decades of the 20th century. The area of San Cristobal was already in the 1920s a nucleus of neighborhoods for workers. It acquired such importance that it was one of the central urbanization areas in Bogota’s growth process. Although since the 1890s there was a construction project for a tramcar, it was only until 1917 that the tramcar was operated. The urbanization of San Cristobal, therefore, did not wait for the tramca, but at the time when the new neighborhoods of the sector were being formed, this means of transport became an urban service of great importance both for the inhabitants of the sector and for the actors that seek to promote the development of the area.
