Authorities in Chile say at least two rail workers were killed and nine others injured Thursday when a freight train collided head-on with another train on a test run just outside the capital of Chile

SANTIAGO, Chile — At least two rail workers were killed and nine others injured Thursday when a freight train collided head-on with another train on a test run just outside the capital of Chile, a rare fatal crash in the South American country.

Police said they were investigating to determine the cause of the collision, which left the test car sitting fully on top of the freight train. Authorities said they detained the driver of the test train and a railway operator for interrogation on charges of reckless manslaguhter.

Photos and video of the scene showed one carriage jackknifed several meters into the air above a badly mangled cargo train. Two dozen emergency vehicles swarmed the tangle of crushed metal as helicopters buzzed overhead in San Bernardo, a district just south of Santiago, the capital. Trains service in Santiago remained suspended Thursday following the crash.

The eight-car freight train was carrying 1,346 tons of copper, Chile's main export, and had some people on board while the other train had 10 workers on board operating a speed test, the state rail company said.

Security camera footage showed both trains traveling at high speed when they slammed into each other. It wasn't immediately clear why the test train hadn't been alerted to the freight train's approach.

“We have to identify what the causes are and take the corresponding measures,” Transportation Minister Juan Carlos Muñoz told The Associated Press.

Authorities identified the two people killed as crew members on the freight train. Another
