The life style in Guatemala is much the same today. Except there is more cars, TV's and computers. The railroad is gone and being systemately stripped by the locals for steel and scrap.
The interchange could only be the border with MExico. That is most southern point that standard gauge from Mexico, US and Canada can reach. Unfortuneately the railroad to the border is shutdown due to damage from a storm that flooded the region a few years back.
There still is talk of building a new standard gauge railroad to reach Panama via Guatemala, El Salvador and Honduras. It just the financing and the return would take a century to pay a return.
