By the end of 1992 ETCE had acquired no less than 31 secondhand Swiss trolleybuses, of several types and from four cities. From Zürich came one additional, later-model (1974-built) articulated FBW in early 1992; from Geneva, 16 articulated trolleybuses (comprising 14 1965 Berna vehicles and two 1975 FBWs); from St. Gallen five two-axle 1970–1975 Saurer vehicles; and from Schaffhausen three 1966 FBWs, of which two were articulated. ETCE carried out a program of heavy rebuilding of 18 Pullmans, much more extensive than the earlier rebuildings and effectively a full rebodying, for use exclusively on its new ETS system; these were renumbered into the series 101–118. The Santiago system opened on 24 December 1991, using four ex-Zürich vehicles (renumbered 501–504) and the first few of the rebodied Pullmans. Within two months, these had been joined in Santiago by eight brand-new Chinese "Shenfeng" trolleybuses (601–608) from Norinco, which ETCE/ETS purchased after evaluating a prototype Shenfeng vehicle in Valparaíso in early 1990. China has had several trolleybus manufacturers, and these nine units for ETCE/ETS were notable in being the first Chinese-built trolleybuses ever exported outside of Asia. Sharing between cities Most of the secondhand Swiss vehicles remained in Valparaíso, some entered service there, and some remain in service there in 2011. Others were used as sources of parts. The three Schaffhausen vehicles all entered service in Valparaíso and never went to Santiago. Three or four of the ex-Geneva vehicles were transferred to the Santiago system for a time, but later returned to Valparaíso. Meanwhile, the Santiago fleet kept its four ex-Zürich and eight Shenfeng vehicles and the 18 heavily rebuilt Pullmans. The Santiago trolleybus system closed in July 1994. ETS suspended service after operation on 9 July 1994, after months of struggling financially in the face of competition from other private bus companies serving the same areas of Santiago, and ultimately service never resumed. Most of the Santiago fleet remained in storage there, as ETCE/ETS initially hoped to revive the service, until being moved to ETCE's depot (garage) in Valparaíso in early 1996. Post-1995 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
