The Monster of Loose Zone
The train passes through a loose zone where everyone becomes loose and lazy and otherwise irresponsible. Tetsuro gets thrown out of the train somehow and the Conductor and the train are too lazy to look for him. Maetel is virtually unaffected. Tetsuro then ends up in a giant trash heap where he is chased by a monster made of trash. Eventually Maetel rescues Tetsuro on an uninhabited garbage planet. When the 999 leaves a much larger garbage monster attacks it but then collapses.

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.
