The second picture has definetly a better composition. I like it very much.
But I believe you could do even better. If I may suggest something:
I don't know how the background looks like but if it's not to busy try some wa from a lower point of view.
Kneel down or even lower. I think this will get you more focus on the rails and allows to to also show more from the trees. Also play a little with DOF. maybe a blurred background would also do well.
Have fun, and I would love to join you, but a little bit far away from Germany
