Well animated for its time and audience. It keeps things rather simple and even surreal visually. The story is episodic and invariably creative. This will appeal to someone interested in a good example of period animation, or someone just looking for something for the children to watch ( that will give them a pleasant creativity boost insted of nightmares ).
As for the story; a young boy in a rather large appartment complex is sent off to the basement for something. While down there he comes accross . . . You guessed it, a secret railroad. He sets out on the old steam train and adventure begins. The train does not emerge in our 'real world' but rather seems to wind its way through some alternate world. More fantasy than science fiction, the story and visuals tend to be surreal. If you like Galaxy Express 999 then you may find this to be its 'little brother'.
Recommended for children and animation enthusiasts.
