However, Xanterra (the primary concessionaire at Grand Canyon NP on the South Rim) purchased the GCR about 10 years ago to build up their NPS concession holdings nationally. Since Xanterra is profit-driven from traditional state and park service income sources (lodges, restaurants, campgrounds, sightseeing tours, etc.) and providing a public service to many non-concession users, such as Amtrak passengers seeking an alternative to FLG, dropping the Williams Junction Amtrak service doesn't surprise me all that much.
