Beautiful shots! As much as I would like them to expand and repair the existing rail network in the US, I like the fact that they are turning a lot of these old lines into walking paths. We have a really nicely maintained one in the city where I grew up. My wife and I walk on it quite frequently.
I imagine repairing the existing railway network can be quite costly unless it can be justified with more usage, otherwise converting them to walking paths aren't such a bad idea either.
The one walking path we have goes just about half the length of our state. It is pretty cool. It runs right along the property of a craft brewery too.
I still can't get over how big places are in America!
It's just crazy!
