Typos: in the third stanza, the first line says "she sat for long in the rain," this doesn't really make sense to me. I know what you are trying to say, but the words are in such a way that it doesn't sound quite right. I would suggest changing the wording to something like "she sat for hours in the rain" or something like that. However, its your poem so you do what you want :) its just my opinion.

Its a very good poem, and one that brings sadness. From what I understand she woke up one day and decided to end her life by jumping in front of a train. Maybe you could have somehow made it so that we could have known why she ended her life - that would have made the poem a little bit more relatable.

Overall, very good poem.
