history, starting on 6 January 2007. TCSA initially reported an increase of at least 30% in its revenue following the reorganization, thanks to its near-monopoly on serving busy Avenida Pedro Montt. However, the situation turned around quickly after complaints from merchants along the street convinced the transportation ministry to permit the return to Avenida Montt of 16 bus routes run by other companies only three weeks later. The trolleybus company's revenue dropped sharply, and it discontinued Sunday service in April 2007. Faced with this unexpected loss of revenue at the same time that it had just incurred the expenses of having to repaint its fleet (to meet the TMV requirements) and expand service (to a second route), the company announced in May that the trolleybus system would close in mid-June. The unexpected news upset many citizens, as the vintage trolleybuses, designated a national historic monument in 2003, had become a cherished local icon. Even Chilean president Michelle Bachelet voiced her support, telling regional transportation minister René Cortázar, "The trolleys can't stop running in Valparaíso", while at a luncheon with Valparaíso's mayor. Negotiations between TCSA and government officials led to agreements that averted the planned closure. Service continued relatively unchanged on the system's longtime Avenida Colón route (802), but the recently revived Avenida Pedro Montt service (route 801) was discontinued once again, on or around 1 September 2007. On 31 October 2007, the historic monument designation given earlier to the Pullman-Standard trolleybuses was expanded to include most of the system's infrastructure, such as overhead wires, support poles and substations. On 4 May 2021, route 801 was restored to operation after an absence of almost 14 years. Maintenance facilities During the efforts to resolve the mid-2007 crisis officials pledged to help TCSA find a better site and facilities for its garage. Until 2000, the trolleybus fleet had been housed and maintained at the city's former tram depot (carhouse), opened in 1904 for trams. However, the property was municipally owned, and in 2000 the city sold it, for planned redevelopment. The trolleybus system's then-owner ETCE was obliged to find other accommodation for its fleet. It was unable to find any suitable enclosed facility that was available near its route, and consequently for several years the trolleybuses were mostly parked on city streets when not in use (including overnight), and all maintenance work had to be done outdoors. In mid-2008, TCSA began leasing a
