Notes: Tangiwai rail disaster - The worst railway disaster in New Zealand's history occurred on Christmas Eve 1953 when the Wellington-Auckland night express plunged into the flooded Whangaehu River just west of Tangiwai, 8 km west of Waiouru. Of the 285 people on board, 151 were killed. The tragedy left a nation in mourning, and stunned the world. OpenStreetMap
