I have received a request for assistance in locating a railway historical society near Bogota, Columbia that might be interested in cosmetically restoring a steam locomotive presently on display but neglected (covered in graffiti). Any suggestions?

If you Google "Tren de Sabana", you'll get a bunch of links for the active narow gauge restoration effort in Bogota.

Good luck to you, and givev my best to Federico Reynales,
