The Queronque rail accident was a head-on train collision that happened on February 17, 1986, on the line between Santiago and Valparaíso in Chile.
[3] Repair work to a bridge damaged in an explosive attack by the FPMR[4] six months previously meant that a single line was used for trains travelling in both directions.
[6] Theft of telephone cabling meant that the phone link between stations was not working,[7] and it was over an hour before rescue teams arrived at the scene of the accident.
[4] The rescue efforts continued until 11:30 the following morning; an emergency hospital room was set up on the platform at Limache station; its speakers were used to ask for blood donors to come forward.
[8] Dictator Augusto Pinochet visited the injured in hospital shortly after the incident and pledged compensation to those affected similar to that in place for road accident victims.
