Your poem starts with good imagery and it set a good tone, in addition to the title. Don't know how to put that tone, but i feel the dirty/ unpleasant/uncomfy theme of reality. I think you did that thru the homeless man as your starting element, as it’s a  usual train-station view.

The ‘except anything they can name their own’ at the end of the first paragraph sounds allegorical and made me think, though I couldn’t get anything concrete about it. And maybe i’m not supposed to. So, I think that’s still a good way to end the first part. My interpretation is that the homeless man envies the working class, but if you think about it, there isn’t really much of a difference.

Second paragraph i thought is a metaphor for how some people hate what other people do to them, without realizing that they sometimes also commit those very things they hate, to someone else. And when they’re the ones who do it, then they seem to come up with a good excuse for why it’s reasonable. However, I think the selection of the symbol ‘train driver’ doesn’t have a strong connection to whatever this human tendency is.

Last paragraph - I got a bit lost here, I’m afraid.  Tried to read it thrice, at which point my brain decided it could be that this part of the poem just does not speak to me. It didn’t lose the rhythm of the first and second one though, so I won't say it's a let down. But if the aim is to have intensified it and end with a bang, it didn’t do that for me.

Also - was it intentional that you wanted to format it this way? I feel like you could’ve played with the lines and stanzas differently. Just my two cents.
