I think that the hellish train in the song is the godless world.
It's coming right at you with complete disregard for the lives it has ruined thus far: "feed the iron horses with mortal remains."
It is hellbent on destroying you: " we stay on this bearing Destined for your derailment"
No individual can overcome it: "No man can take the helm of This chaos parade, this havoc train To board this evil engine with no Dead man's switch!"
Yet its evil will not prevail in the end: "destined to fail."
