A classic vanishing point. It all worked but the sky did not cooperate for you. In this case I think the sky could be cropped out - putting the vp close to the top.
A quite common idea, and for me too rigid in its application without adding anything new. The usual recourse of such image is in high quality, but I'm afriad the contrast and light and suspect resolution around the tree don't do you any favours here. 4
The problem with using a cliche subject is that you really need a new take on it to stand out. The double set of tracks partly meets that criterion, but among som many rail shots this gets lost, nice as it is.
Great attempt but there are focusing issues. I also think this could have been composed a bit better like if you were a bit lower to the ground and maybe more biased towards one pair of tracks rather than biased towards the middle.
