It doesn't use the magic in a creative way. Why even go through all the trouble of making something like this when you can just make a normal coal trains? Maybe at most conjure coal to power it? If it runs on magic, why limit it to moving on the ground with a fixed rail?

No one would bitch if it was well thought out and cool.
