A well done story with terrific and creepy detail! The transition from the security of the train's interior to that of the carousel was done with your fine hand. Poor Joelle, pulled into the trap of the deviant old man and now imprisoned within his horrid tin.
There were not only horses there, but a wonderful caterva: hippos, giraffes, gorillas, cranes, an enormous tarantula, a cancerber, a hydra; the eyes of a tropical Medusa that left her petrified..
This reminds me of a carousel I rode when I was 10, minus the tarantula and cancerber. Thank you for sparking that memory while adding to the otherworldly feel of your story!
