Rail tunnel under Mexico-California border

[Adlington]

Unfinished, unfortunately... or may be fortunately, given the intended use....

Officials have found what was described as a “sophisticated” cross-border tunnel likely designed for drug smuggling between the US and Mexico, that included a rail system and a solar system to provide ventilation and lighting.

US agents determined that the tunnel’s entry point included a shaft that was approximately 31 feet deep, with a total length of 627 feet, of which 336 feet were inside the United States. Agents reached an exit shaft that went approximately 15 feet up towards the surface, but did not yet have a an exit point into the US.

I could not find any information on the technical side of the rail system. Gauge? Motive power?

The greenies will be happy to know that a solar panel system had been used to run the electrical, lighting and ventilation systems in the tunnel.

its quite something when the Mexican drug barons are further ahead than the current US government on environmentally friendly solutions....
