Trains have a much higher capacity. Most people currently drive the distance which leads to more accidents and a lot of lost time. $100bn is too expensive to make sense but I don't understand why it should cost that much. There are not that many tunnels needed, esp. if you start/end north of LA and south of SF. European rail projects are also expensive but still a fraction of the cost.
