Hi Jenna, for what it's worth (I'm no expert btw) the frst thing I thought was "That looks like it's meant to be a still from a movie".
I could spend a quite a while looking at this, you have chosen a good depth of field, and the exposure looks perfect. The light is very good and It has an "old fashioned" feel to it which I think is helped by the colour saturation levels which really suit the style/subject matter.
I find the composition generally very pleasing with all the leading lines taking my eye on an enjoyable meander down the platform passing the milk churns & lamposts... all the way to the "guard?" standing at the far end. Great timing btw! I do have to agree with the others though that the bottom probably would have looked a lot better if you could see some more of the train, do you have any image data there so that you could try it with a slightly different crop?
With that said it's still good work though, keep it up.
