Locally known as paraderos (English: bus or rail terminal stops), these intermodal passenger transport stations allow commuters to transfer between different modes of public transit, generally between rail and bus systems.

In Mexico City, their operations are supervised by Organismo Regulador de Transporte (ORT).

Due to the dissolution of the state-owned company Autotransportes Urbanos de Pasajeros Ruta 100 (colloquially known as Ruta 100 [es]), it was decided to grant the transportation concession to private companies, thus decreeing a Transportation Law.

Between 1996 and 2002, the control of the CETRAMs changes from one agency to another within SETRAVI, until it ends up being administered by the General Directorate of Transportation Regulation.

By 14 December 2010, the CETRAMs were decentralized and their operations were transferred to the Organismo Regulador de Transporte (ORT).
