I'm surprised I haven't read any talk of, or even speculation about the idea of the Boring Company getting involved with the tunneling required for CA's high-speed rail project (for the Pacheco Pass and Tehachapi Mountains segments).

My guess is that perhaps very different tunneling technology is required given the geology or something. Or maybe it's just that Elon Musk hates trains and loves cars way too much.

TBC's "innovation" was to make smaller tunnels, which is useful for things that can be done in smaller tunnels but is useless for any mass transit activity because they're simply not large enough.

(TBC's boring machines were previously used to bore utility and sewer tunnels.)

TBC makes small tunnels, enough for an SUV, likely not big enough for a long distance train.
