I'd be very surprised if they attempted to build anything other than an electric train. If they're trying some sort of "hyperloop" I would share your skepticism, but as I understand it the Boring Company is about boring tunnels more than anything else (at this stage anyway.) Is an Elon Musk company capable of boring a regular tunnel and putting a regular train in it? I don't know the current state of their boring machines, but it seems like it should be feasible.
