At least 40 people were injured Wednesday in Sao Paulo when two subway trains crashed, the Fire Department said, dpa reported.
Ricardo Peixoto, who supervised rescue efforts in Brazil's industrial capital, said none of the injured were in serious condition.
The crash, whose cause is yet to be established, happened at around 9.30 am (1230 GMT) between the stations of Carrao and Tatuape, in Sao Paulo's impoverished east. The injured were taken to nearby hospitals.
Rescue efforts caused major traffic jams.
