For nearly 40 years, the fleet comprised solely Pullman-Standard trolleybuses, a combination of new-to-Valparaíso 1952-built Pullmans (the 700-series) and, from 1954 on, a number of ex-Santiago Pullmans, built in 1946–1948 (the 800-series).
 All had electrical propulsion equipment by General Electric.
 As of 1986, the total number of trolleybuses available for service was 23–24.

Under a program started in late 1986 and continuing until 1989, ETCE rebuilt the bodies of some of its 800-series vehicles with more modern front ends and, in some cases, sides and backs also.
 The remaining 700-series vehicles were not rebuilt.
