N.Y. Railroad Law § 78-a: Electric or battery-powered markers

§ 78-a. Electric or battery-powered markers. 1. Any railroad using a

passenger, mail, work, or wreck train shall equip the last car of each

such train with electric markers of sufficient candle power to be

visible for a distance of three thousand feet under normal weather

conditions. Battery-powered, flashing-type, or constant burning markers

shall be deemed sufficient compliance with the foregoing requirement.

2. If, in any particular case, exemption from any of the requirements

herein is deemed necessary by the railroad concerned, the commissioner

of transportation may grant the application of such railroad, for such

exemption when accompanied by a petition setting forth the conditions

existing and the reason why such exemption is asked. Any exemption so

granted shall be limited to the particular case covered by the petition.
