A subway train derailed near a children's playground in Santiago, Chile, last night, smashing parked vehicles and crashing into an apartment building.

News agency Reuters reported the train was not carrying passengers at the time of the accident, but was making its way to an above-ground storage facility.

No injuries were reported but local media said the conductor was in a "state of shock" and taken for a medical check, Reuters said.

Residents living in the damaged apartment building said it was a miracle nobody was hurt on the ground especially considering children often played in the park.
