 During the 1993 suspension of trolleybus service, construction of the planned extensions proceeded, east to Ciudad Universitaria and west to Calle Sánchez de Loria.After a suspension of more than a year, the trolleybus system reopened on 25 January 1994, now with an entirely new fleet, a new operator (Ecobus) and extended at both ends of the single route, still line K, which now operated from Ciudad Universitaria to the intersection of Calle Mendoza and Calle Sánchez de Loria.The new trolleybuses entered service still wearing the red-and-cream livery they had been given when built, for Belo Horizonte, but this was short-lived.
