Testing Sao Paulo's transport network

The Fifa World Cup's opening game takes place in Sao Paulo's Arena Corinthians on Thursday, as Brazil play Croatia.

City authorities are waiting to see if metro workers will resume a strike on the day. If that happens, just how easy will it be for tens of thousands of fans to get to the stadium?

One option would be to take the overground train.

BBC Brasil's Luis Barrucho filmed the journey on his smartphone.
