Firefighters inspect a commuter train that failed to stop and crashed at the end of the line at a railway terminal in Buenos Aires.

Story highlights

Five of the injured sustained fractures

Cause is not known

It comes 4 months after 3 people were killed when two trains collided

CNN  — 

At least 80 people were injured Saturday morning when a train crashed in a Buenos Aires station, Argentina’s Security Secretary Sergio Berni told state news agency Telam.

Five of the injured sustained fractures, Berni said. The cause of the crash was not immediately known.

Saturday’s crash comes four months after two commuter trains collided near the Argentine capital, killing at least three people and injuring hundreds more.

“In addition to solidarity and pain, I feel anger and impotence,” President Cristina Fernandez de Kirchner said in June. “Because the truth is, we are putting everything (into the train system), not just economic resources and investment, but also time and human resources. When things like this happen, it hurts all of us.”

And in February 2012, a commuter train on the same rail line crashed into a barrier at a station in Buenos Aires, killing 50 people and injuring hundreds.

That crash sparked a criminal investigation. More than two dozen suspects, including former government officials, were accused of mismanagement and defrauding the public.

Now, a government consortium oversees the train line, rather than a private company.

In 1970, 200 people died when two trains crashed north of Buenos Aires.

Eight years later, 56 people were killed when a train hit a truck in Argentina’s Santa Fe province, the state news agency reported.
