There are a couple of places where the narrow gauge U&N grade still exists. The Corrine Branch which left the UN grade just North of Brigham City, UT and a longer stretch which can be seen on Google Earth from a large gravel pit just north of Deweyville, UT and can be followed from there around the end of the Wellsville Mts, over Collinston Hill to where it disappears into farm fields in Cache Valley. Later the Utah-Idaho Central, a standard gauge interurban line that ran from Ogden to Preston, Idaho, used the U&N grade over Collinston Hill. All remaining portions of the U&N grades are on private land and are inaccessible.
