Poem Without Title, Not "Untitled" As Per Convention

For My Workshop, who would understand this poem

Stop saying the train is a metaphor!
It's real, damnit.
I was on it; it was going somewhere actual.
I really disembarked--
people saw me return.

It is symbolic.
Perhaps that's what you were meaning?
But, it is not the idea of distance.
I rode for miles and miles encased
in steel, hearing the wheels scrape against
the tracks, and true sparks flew.

And when I leaned back I dreamt
the way one can only dream on a locomotive--
lulled, conveyed to destinations where
I was fully expected to show up for real.
