All aboard the samba train in Brazil

The month of December in Brazil has become a time for celebrating the roots of samba music, and the ''samba train'' has become a popular tradition.
In Rio, the birthplace of the sound, the train takes bands from the heart of the city out to Oswaldo Cruz, a suburban neighbourhood, in celebration of the area's musical heritage.
Julia Carneiro went on board.
