2017. Service changes after 1990 The Avenida Pedro Montt route was discontinued in 1991, leaving only the Avenida Colón route in service. ETCE tried reinstating the Pedro Montt service twice since then, in October 2002 and January 2007, but withdrew it again just a few months later in both instances, after finding that competing service run by other bus companies along the same street made that corridor a money-loser for ETCE. A new company named (TCSA) was established in 2000, with 40% ownership by ETCE president Pedro Massai. ETCE remained the system's overall owner and operator, but some of its assets, including the overhead trolley wires, were transferred to the new company. During a three-week suspension of service in August 2002, caused by a drivers' strike, some 20,000 residents signed a petition urging the two sides to reach agreement so that trolleybus service could be restored. The city's largest-circulation newspaper, , also published an editorial in support of restoring and maintaining the trolleybus service. Trolebuses de Chile, S.A. became the operator of the trolleybus system in early 2007. 2007 improvements, upheaval The trolleybus system underwent several changes in early 2007 in connection with the implementation of a regional public-transportation coordination program called the (TMV) by the regional ministry of transportation. TCSA reinstated the former Avenida Pedro Montt route in January, after the ministry granted the company near-exclusive rights to provide transit service in that corridor. The company's now-two routes became numbered 801 (via Av. Pedro Montt) and 802 (via Av. Colón), under the TMV plan, which assigned route numbers to all bus and minibus routes in the region; previously, they had been unnumbered. Both routes continued to terminate at Aduana and Barón. The TMV also required that operators apply a uniform paint scheme to their vehicles, with different colors for different (business units). TCSA's routes were the sole routes in Unidad 8, and the company was required to repaint all of its trolleybuses into a common livery of green-and-cream, which was completed in April 2007. Until then, some of the secondhand Swiss trolleybuses (acquired 15–16 years earlier) had retained the paint schemes of their cities of origin, while others, and some Pullmans, had been wearing advertising liveries; the latter were also no longer allowed under the TMV. The company also introduced Sunday service (on both routes), for the first time in the history of private operation, and perhaps the system's
