Santiago Metro Line 1

One of the most memorable and tragic events in the history of the Santiago Metro was the June 16, 1986 terrorist attack, which took place on Line 1.[5] At 6:56 a.m., the Manuel Rodríguez Patriotic Front, a group opposed to the government of General Pinochet, attacked Tobalaba station with C4 bombs. The bombs exploded and caused the death of one passenger, injured another six, and left one NS-74 train destroyed. Because of this, Metro S.A. (the company that operates the Santiago Metro) decided to replace that trainset, however Alsthom Groupe Brissonneau wasn't producing trains at a fast enough rate, so the company turned their attention towards Concarril, who supplied the Santiago Metro with one NS-88 trainset as a replacement. The destroyed train remained out of service until it was rebuilt by Santiago Metro workers between February 27, 1989 and December 14, 1990, going back into circulation in 1990. The train now bears a commemorative plaque for the attack and its reconstruction.

A series of protests in October 2019 resulted in major damage to the metro network. Line 1 (which suffered a minor amount of damage compared to lines 4 and 5) was closed on the weekend of October 18 of that year, and resumed partial service two days later between Pajaritos and Los Dominicos; full service was expected to resume in the first half of 2020. San Pablo, Neptuno, and Baquedano stations suffered moderate damage in the protests, and as a result those three stations would temporarily close (resulting in an ability to transfer between lines 1 and 5). However, the Baquedano station has remained closed to the public since the beginning of the protests, however On April 8, 2020, the combination of both lines was enabled, with their accesses closed until May 4 of the same year. Finally, Line 1 was fully operational again on July 25, 2020, with the reopening of the San Pablo and Neptuno stations.
