An act of true heroism.

On Sunday, July 5, an Australian man jumped onto the train tracks to save his granddaughter when the baby's stroller accidentally rolled off the platform and into the path of an incoming freight train — and the entire ordeal was caught on surveillance camera.

Thankfully, neither person was hurt in the incident. According to local police, the 18-month-old baby suffered swelling to the forehead and cuts to her knees from the fall. Her grandfather was not injured.
