SAO PAULO, Brazil (AP) _ A commuter train slammed into another that had stopped at a station outside Sao Paulo, killing at least nine people and injuring 115, authorities said Saturday.

The collision occurred around 9 p.m. Friday in Perus, about 40 miles northwest of Sao Paulo. The Sao Paulo Metropolitan train company blamed the crash on a power failure that left the train's braking system inoperable.

Four cars of the train were destroyed. Firefighters removed seven bodies from the wreckage and continued to search for victims. Two more people died at the hospital.

State Gov. Mario Covas and other officials were headed to the site of the accident to hold a news conference later in the day.
