Ferrocarril de Rio mantanas....where did it go

I was looking back through the 9/03 model railroader at Malcolm Furlows FDRM and wondered what ended up happening to it. I havn’t seen any recent pics in the mags or elsewhere. In the article his track diagram shows the future extensions, but I havn’t seen anything else since then. I’d sure like to see what the rest ended up like.
