It’s got a bunch of fairytale like stories at the beginning. One involving anthropomorphic railroad signals in love.
The main story however is about Giovanni and his trip on the Galactic Railroad with Campanella.
Most of the story is fever dream, dream logic style stories involving flat cranes and other things like that. In the end Giovanni gives no shits about Campanella.
I really don’t get why thisi s a classic other than people don’t really understand that it’s mostly nonsense?
