The Celestial Railroad (2006)

Welcome aboard the fantasy train in the stars! "Fantasy Railroad in the Stars" is a fantastic journey of a boy, Giovanni, in a dreamscape created into a colourful full-dome CG animation picture with inspiring background music. Based on the famous Ginga Tetsudou no Yoru story written by Kenji Miyazawa in the early 20th century, Kagaya, a digital fine artist, has breathed new life into the unique imaginary world using creativity and precise astronomical knowledge. The starry sky is depicted as the Celestial Field made up of a river, a field of silver grasses, flowers, birds, survey towers, railway signals and more. Across this amazing beautiful scenery, the Celestial Railroad runs along the Milky Way. It is a fantasy world in full colour, but designed with scientific accuracy.

Unfortunately the movie The Celestial Railroad is not yet available on HBO Max.
