N.M. Stat. § 77-16-16
Railroads; fencing of lines; damage.
A. Every railroad in this state whose lines of road, or any part thereof, are open for
use and every railroad company formed or to be formed shall, within six months after
the lines of the railroad or any part thereof are open, erect and thereafter maintain
fences on the sides of the railroad or the part thereof so open for use, suitably and
amply sufficient to prevent cattle, horses, sheep, mules, burros and hogs from getting
on the railroad, except at the crossings of public roads and highways and within the
limits of municipalities and shall also construct, where not already done, and maintain at
all public road crossings now existing or hereafter established cattle guards suitable and
sufficient to prevent cattle, horses, sheep, burros, mules and hogs from getting onto the
railroad. If any railroad fails to construct and maintain fences and cattle guards as
directed in this section, the railroad shall be liable to the owner for all damages resulting
from injury or death caused to any livestock, including reasonable attorney fees, on
order of the court should legal proceedings be commenced by the owner. Should the
New Mexico livestock board be unable to determine ownership of livestock crippled or
killed by the railroad within thirty days of the date it first receives notice of such injury or
death, by report or otherwise, then the board may institute legal proceedings in the
name of the unknown owner in any court of competent jurisdiction and recover
damages as provided in this section, and the proceeds shall be disposed of as provided
for under the laws pertaining to estrays.
B. In the event that a fence is in a condition of neglect, disrepair or nonexistence,
the adjacent landowner may contact the railroad supervisor or the owner of the right of
way by certified mail, return receipt requested, and demand repair or construction to the
legal standard provided in Section 77-16-17 NMSA 1978. Within thirty days thereafter,
the railroad shall commence construction or provide proof of intent to comply, and after
ten more days, if the railroad has failed to commence construction or to comply with
agreed-upon terms of construction or repair, the adjacent landowner may repair,
construct or cause to be repaired or constructed the fence at the expense of the railroad
calculated at the cost of commercial rates common to the area. If the railroad fails to
comply within thirty days of presentation of proof of cost, the landowner shall be
compensated in an amount equal to two times the amount of the presented proof plus
any cost of litigation, including attorney fees.
C. State-owned railroads and narrow-gauge and recreational railroads are exempt
from the provisions of this section.
