Rendón Peniche purchased the rights to the Mérida-Izamal line in 1884. In 1887, just before his death, he sold his combined Mérida-Progreso e Izamal railway to a group led by Olegario Molina. It was sold to the FCUY in 1902.

Francisco Cantón sold the railway in 1902 to the Escalante family, who sold it to the FCUY later that year. The railway reached Valladolid in 1906; the Dzitás-Tizimín rainal was finished in 1913.

Although construction began in 1879 on two lines from Mérida and Campeche, intended to meet in Calkiní on the Campeche side of the border, much of the work had to be redone by a group of investors led by the Peón y Peón family, who purchased the concessions in 1889. The company was renamed the Ferrocarriles Peninsulares. Construction on the main line was not completed until 1898, and a Muna-Ticul ramal was not finished until 1904. The company was sold to the FCUY in 1902.

Rodulfo G. and Olegario G. Cantón purchased the concession in 1880. Olegario sold his share to his brother in 1892. The family business became a sociedad anónima in 1895. The railway reached Peto in 1900, and the Acanceh-Sotuta ramal was finished in 1912. In 1908, during the financial panic, Rodulfo sold the company to the FCUY.
