Video: Moment driverless monorail rams through fallen crane in Brazil

A driverless monorail train collided with a construction crane in Sao Paulo, Brazil, sending the crane crashing onto a busy street, terrifying footage shows. The fully automated train struck the crane at speed, with no onboard driver to spot the obstruction hanging over the tracks. 

Despite the impact, no passengers aboard the monorail were injured. However, the crane operator sustained injuries in the incident. Motorists travelling along the road below scrambled to escape the area as the crane came crashing down, narrowly avoiding a potentially more serious accident.
