I don't think the good citizens of Raton, NM, really appreciate their town being referred to as a "wasteland". Any good dog owner will clean up after their animal, despite any disability. And the area around the station is quite heavily trodden, what with buses, cars, smokers, and thousands of Boy Scouts each summer. Do you want people leaving feces at your local train station?
Also, BTW, most major stations are NOT owned or operated by Amtrak, and as such, it is not's Amtrak's responsibility to maintain the washrooms; contact station management about that.
