LOTM Storyline
From 1973 to 1991, he mainly pulled passenger trains.

On September 2, 1991, his self-awareness was disabled in order to prepare for his final run. A deliberately derailed nuclear container was dragged onto a branch line which he was diverted into. His driver pushed the throttle all the way forward and climbed out of the cab just as Zemi set off again. After barreling for over a mile (1.6 km) down the track with nobody on board, he smashed into the nuclear box at 113 mph/182 kph which exploded. The crash looked deadly, but the important thing was that the container remained intact. After this was confirmed, engineers had proved to the characters of the world that they had designed a nuclear storage device that could survive the ultimate disaster.
