The main depot switching yards of the Rio de Janeiro Metro, located near the D. Pedro II main railroad station. The trains seen in this photo were the first ones built for the Rio de Janeiro metro by MAFERSA, in the early seventies - they can be easily recognized by their windshields divided in two halves. Photo shot by Newton Carneiro; this copy was kindly sent by Jorge Alves Ferreira Jr., from Juiz de Fora MG.
