Very nice track !
The cover art with the train in space reminded me of Galaxy Express 999 which is great (it is also my favourite manga so I might be a bit biased) and the track has a great vibe throughout.
I thought that the inverted drums were a bit weird at first, but as time went on, I started to notice that they sounded a lot like the chugga-chugga sound from a train, which is really fitting for the concept you went for (maybe this is the reason you went with this theming now that I think about it).
Anyway nice track so good job !
