Morgan Jones was 6, travelling by train through Kaikoura when he fell through a safety rail and onto the tracks below.
He was left with horrific injuries - blind, with his right leg amputated and one side of his body partially paralysed.
Tranz Rail was taken to court over the accident, but was cleared of criminal negligence. A settlement was reached with Jones' family outside court.
Now 29, he has been able to do more than he thought was possible - including competing in a dance competition and taking on an adventure trip.
He took home a trophy from the NZ World Latin Dance Cup competition last month - although he won by default as the only dancer in the category.
