In Brazil, in the town of Itapecuru Mirim, located on the margins of the BR 135 highway, there is the quilombola community of Santa Rosa dos Pretos. They have suffered many violations of their social, economic and environmental rights, due to the operation of the railway, especially since the duplication of the Estrada de Ferro Carajás (EFC, in Portuguese) is under construction. The impact of the construction can be seen on the silting of the igarapés, the noise and air pollution. Besides that, there is a bigger number of trains passing through the area, which made the crossing more difficult and increased the number of accidents.
