Colombia mining firm Cerrejón said that its railroad was blasted in a terror attack on 13 October 2013, resulting in the derailment of 43 cars of a coal-carrying train.
The company noted that the explosion, which took place near the 93km mark, damaged the railway line and also overturned the truck of its protection division staff.
A train transporting coal from the mine to Puerto Bolívar was derailed and no one was reported to have been injured in the attack.
Cerrejón is a mining and transport complex in La Guajira, jointly owned by the subsidiaries of BHP Billiton, Anglo American, and Glencore Xstrata.
The property includes a 150km railroad in addition to its thermal coal open-pit mine and maritime port, and claims to be the largest private exporter in Colombia.
The track, which is claimed to be the only wide-gauge railroad in Colombia, links the mine to Puerto Bolívar.
A military source told Reuters that the attack was carried out by the country’s main rebel group, the FARC.
"Cerrejón will continue to work under the strictest respect for the law, and in maintaining its effort to do responsible mining with workers, the environment and communities neighbouring the operation," the company said.
