Most of the ex-ETS fleet remained stored, unused, in Valparaíso for several years and was eventually scrapped.
 The few Geneva trolleybuses that had run briefly in Santiago entered service in Valparaíso soon after returning.
Otherwise, the only ETS-system trolleybuses that entered service in Valparaíso did so only several years later:  two of the Zürich vehicles in 2003, one rebuilt Pullman (116) in 2004 and two Shenfengs (603 and 607), in 2004 and 2005, respectively.

The five ex-St.
Gallen trolleybuses never performed to ETCE's satisfaction under the low overhead-line voltage in Valparaíso, about 500V–550V  as compared with 600 V in St. Gallen, and they were used in service only briefly – most in 1992 only, with one (142) in sporadic use until 1995 or early 1996.
 They then were stored until being scrapped in 2008, except for No.
142.
That sole remaining St. Gallen vehicle was installed at Barón terminus (on Avenida Argentina at Calle Chacabuco) in a semi-permanent arrangement, after being extensively modified inside for use as a sales outlet for tickets and souvenirs and for use by drivers and supervisors.

By 1992 only one of the older (1946–1948) Pullmans remained unrebuilt and still serviceable, 1947-built No.
814.
 ETCE's longtime president, Pedro Massai, decided to keep No.
814 in original form, due to its appeal as a heritage vehicle, No.
814 having become the oldest unmodernized trolleybus still in normal service anywhere in the world.
 Pullman 814 was damaged by fire in August 2003, but ETCE repaired it, and the unique vehicle returned to service in December 2003.
 It remains in regular service in 2017.

In July 2003, the system's 15 remaining Pullman-Standard trolleybuses, built between 1946 and 1952, were accorded National Historic Monument status by the Chilean government's Consejo de Monumentos Nacionales, the formal decree of this being signed on 26 September 2003.
 They are the oldest trolleybuses still in regular service anywhere.
 Also, Valparaíso has long been the only city in the world where Pullman-built trolleybuses still operate in revenue service.
