The Granville railway disaster occurred near where I live. 84 people were crushed to death when a concrete overpass collapsed onto a train after it derailed and crashed into its support beams. It is the worst railway disaster in Australian history. I wasn't alive at the time, but the train I catch to work every day passes under the new bridge on the same length of track.
