The Idle One's Mirror
The 999 stopped on the planet Idle One's Mirror, where everything is automated by machines. Tetsuro disembarked the train alone, and was taken by an automated taxi around the city. Once the taxi brought him to a residential area, he found out that the all residents are obese from the lack of physical work.

Galaxy Express 999
After witnessing the death of his mother and being left for dead at the hands of Count Mecha, ten-year old Tetsuro Hoshino is awakened by a mysterious woman, Maetal. In exchange for only his company, Maetal offers him the ride of his life on the Galaxy Express 999. It is said that those who travel aboard the legendary train to the end of the line can receive a free mechanical body and with it, immortality.
Impoverished and alone, Tetsuro leaps at the opportunity and joins Maetal on a quest that will span the cosmos. As the Galaxy Express 999 makes its way across our solar system and beyond, Tetsuro is drawn deeper into a dangerous universe where peril lurks at every stop.
