Ginga Tetsudou no Yoru

銀河鉄道の夜

Based on a short story by the popular children`s writer Kenji Miyazawa, Galactic Railroad offers viewers a slow-paced, dreamlike journey through space and time. When Giovanni, a lonely boy in a hill town, goes to get milk for his ailing mother, he finds himself crossing the Milky Way on a faster-than-light steam railroad. The stations he visits in various constellations, like the planets explored by St. Exupery`s Little Prince, offer curious adventures and an assortment of human "types." Reality and fantasy blur aboard the train, and its travels across the light-years sometimes suggests the journey through life. The characters are depicted as cats, presumably to avoid the problems of animating humans.
