N.J. Stat. § 48:12-139
The purchaser or lessee and his associates or assigns not less than 3 in number, may within 18 months after the sale or lease, organize as a railroad company under a different corporate name from that of the former company by filing and recording in the office of the Secretary of State a certificate that they accept the charter of the company whose property has been sold or leased and setting forth the further particulars required in a certificate of incorporation under this Title, so far as applicable. Such company shall have all the powers and franchises and be subject to all the restrictions, limitations and conditions of the former company.
In lieu of such acceptance of the former charter the purchaser or lessee may form a railroad company under the laws of this State at any time after the sale or lease. The new company may take conveyance of and operate such railroad with the franchises and powers by this chapter conferred in lieu of those granted by special charter.
