One can read this poem as one entire sentence, assisted by some form of paraphrasing, which i believe gives it more character; which interestingly relates to the emotional attachment presented throughout. Loved it.

So, the way I interpret this is this is a couple who has lust pulsating at the moment,they are in a railway station and have to put their feelings aside for now. One has to leave but know that they will meet again soon and will resume back to the passion they felt.

Awwww.... how sweet is this:)
