This abandoned railway line runs through a sparsely populated area of northern New Mexico, and was used to access coal mines along York Canyon. The coal mines closed during the 1990s, leaving no customers along the line.
At Colfax, the York Canyon Branch is still in irregular use, as it is currently used for car storage. The line branches from the mainline at French, NM; the tracks around the area are also used for car storage.
Also at Colfax, this line crosses the also-abandoned line bewteen Koehler Junction and Ute Park.
