You have beautifully rendered this movie and successfully created an appetite in me for it.

The concept of a self sustaining train powered by its continual motion isn't entirely folklore/impossible...

Self sustaining systems already exist, and with the advances in AI technologies, we could have systems that would never breakdown or need maintenance...very possible...

This is a captivating piece I must say...didn't know when I got to the end.
