At least 90 injured after passenger train hits boxcar, derails in Argentine capital

At least 90 people were injured in Argentina's capital when a passenger train struck an empty boxcar on the tracks and derailed Friday, authorities said, a rare collision that fueled questions about basic safety.

The train was on its way from Buenos Aires to the northern suburbs when it derailed around 10:30 a.m. on a bridge in the trendy neighborhood of Palermo, safety officials said. Authorities said it was not immediately clear why the empty boxcar had been on the rails but that they were investigating.
