of narrow-gauge railway material was delivered to the General Vega Camp at the port of Vigía Chico.

When General Ignacio A. Bravo (1837–1918) was expelled from Santa Cruz, the Mayas began to destroy the railway.

In 1918, General Venustiano Carranza granted the Mayan leader Francisco May a license to use the narrow-gauge railway to transport natural rubber.

On 1 February 1927, the President of the Republic Plutarco Elías Calles gave the order to rebuild the former military track.
