After seeing The Life of Gusko Bidori, today I watched this wonderful anime movie from 1985 and the main characters look the same as the characters from Gusko Bidori XD
But anyway, Night on the Galactic Railroad is beautiful. It's deep and sentimental, cute but also sad, and most of the film is set in an imaginative sky of heavens. It's not exactly action or comedy, but it's a wonderful animation with spiritual themes and I love it so so so much. You can find both the English dub and English sub on YouTube. It's also known as Night on the Galactic Express.
