N.J. Stat. § 48:12-125
Any railroad company may, subject to the provisions of section 12A:7-309 of the New Jersey Statutes, by giving notice to a person offering goods, merchandise or baggage for transportation on the railroad or in the vessels of the company, limit its responsibility as carrier thereof to $100.00 for every 100 pounds weight, unless such person shall pay to the company by way of insurance for any additional amount of responsibility to be assumed, such rate as the company may charge therefor, not exceeding the legal rates for transporting 100 pounds for every $200.00 of additional responsibility assumed on each 100 pounds, and at that rate for a greater or less quantity.
A general notice of such limitation, placed in a conspicuous place at or in the office of the company where goods, merchandise or baggage is usually received for transportation, and inserted in a bill of lading or receipt given for the goods or merchandise, and in the tickets delivered to passengers, shall be sufficient notice under this section.
