Does anyone have a site map of Grand Canyon Railway RV Park?

I just was there in the line of back ins against the fence-and the railroad track. I liked it for what it was- a jumping off point for the train trip (just a few minute walk) . Restrooms very clean, and the facility was well maintained. Paved sites in good shape. There were a couple loud trains over the two nights I was there, but slept well for most part. You may find it quieter a few rows from the tracks.
