From and after January 1, 1950, a person, firm, or corporation operating or controlling a railroad shall equip each of its track motor cars used during the period from 30 minutes before sunset to 30 minutes after sunrise with:
(1) an electric headlight of such construction and of sufficient candlepower to render plainly visible at a distance of not less than 300 feet in advance of the track motor car a track obstruction, landmark, warning sign, or grade crossing; and
(2) a rear electric red light of such construction and of sufficient candlepower as to be plainly visible at a distance of 300 feet.
Upon request of the section lead supervisor in any section operated by a railroad referred to in subdivision 1, a track motor car must be equipped within 90 days with a windshield and top wide and high enough to reasonably protect the employees from weather. However, a railroad company is not required in any one year to equip more than an additional 25 motor cars with that equipment.
A person, firm, or corporation operating or controlling a railroad and using or permitting to be used on its line in this state a track motor car in violation of this section is guilty of a misdemeanor.
