After the 1973 military coup, the new Pinochet administration reduced funding for government-run public transit, and the two trolleybus systems both deteriorated quickly. ETCE abandoned its Santiago trolleybus system in the latter half of 1978. The Vetra trolleybuses had been less reliable and had all been scrapped by this time, but ETCE transferred its remaining Santiago Pullman trolleybuses to Valparaíso, where some were placed in service and the remainder provided a supply of parts to keep the others running.
