This abandoned railway line was supposed to bypass the 4.03% grades of Raton Pass, but was obviated by the 1909 Belen Cut-Off.
The ATSF built a line from Boise City, OK to Clayton, NM; from Clayton, ATSF gained access to Mount Dora via trackage rights on the Colorado & Southern (now BNSF). Out of Mount Dora, ATSF began to build a line through Farley to connect with their mainline at Colmor. However, building west of Farley meant crossing the Canadian River, and since the Belen Cutoff had already been completed, the new line was considered unnecessary. Thus, the Colmor Cut-off was abandoned, a mere 35 miles shy of its destination; the existing tracks were removed in 1942.
Today, one can still see where the right-of-way abruptly ends about one mile west of Farley.
