A rail car from the E.F. Madeira Mamoré. Unfortunately there is no technical info about it. They were assembled in Brasil at IRFA - Indústrias Reunidas Ferro e Aço ("Iron and Steel Reunited Industries"). A similar model can be seen at the Viação Férrea do Rio Grande do Sul. According to Paul Waters, the two E.F.M.M. units were built in 1946; they received the name of Presidente Vargas and Presidente Dutra.
