Servicio de Transportes Eléctricos del Distrito Federal (STE) (Spanish for Electric Transport Service of the Federal District) is a public transport agency responsible for the operation of all trolleybus and light rail services in Mexico City. As its name implies, its routes use only electrically powered vehicles. It was created on 31 December 1946 and is owned by the Mexican Federal District government. STE is overseen by a broader Federal District authority, Secretaría de Transportes y Vialidad (STV, or Setravi) (Secretariat of Transportation and Highways), which also regulates the city's other public transport authorities, including Sistema de Transporte Colectivo (STC, the Mexico City Metro system), Red de Transporte de Pasajeros del Distrito Federal (RTP, diesel bus network) and Metrobús, as well as other forms of transportation in the district. STE's passenger vehicle fleet consists exclusively of trolleybuses and light rail vehicles, and in 2007 its network carried 88 million passengers, of which 67 million were on trolleybus services and 21 million on light rail.
STE was organized in 1947, to replace the privately run Compañía de Tranvías de México (Mexico City Tramways Company), operator of the city's tramway/streetcar network, but did not completely take over the assets and operations of that company until October 1952. STE also took over the Compañía de Ferrocarriles del Distrito Federal (Mexico City Railways Company) at that time. The agency introduced its first trolleybus route in 1951. To replace worn-out streetcars, STE acquired 274 used PCC cars from U.S. transit companies that were downsizing or abandoning their streetcar systems. Similarly, as it expanded its trolleybus network, the agency turned to American and Canadian transit companies as a relatively inexpensive source of vehicles, acquiring almost 800 secondhand trolleybuses from several different cities in those countries between 1956 and 1977 and later 37 from Edmonton in 1987. These have all since been replaced by trolleybuses built new, in Mexico, by Mexicana de Autobuses SA (MASA) or its successor, Volvo.
