Linha do Norte was built by different societies in different eras.
A small part of this line was one of the oldest rail connections in Brazil and was constructed by the Baron von Mauá in 1854 . This route connected Porto de Mauá (Guia de Pacobaíba) with the Raiz da Serra station (Vila Inhomerim).
From here the extension to Petrópolis and Areal was made between 1883 and 1886.
In 1926 the line was extended to Barão de Mauá (train station in the center of Rio de Janeiro ) and a connection between Vila Inhomerim and Três Rios was added in the mid-1960s.
Todays situation
Today the entire section between the center of Rio de Janeiro and Vila Inhomerim is used by suburban trains.
