>The first Japanese Shinkansen train went over budget by 100%, but nobody remembers that anymore. Instead they talk about how wonderful the Shinkansen trains are.
HSR is at 300% of original budget without even a credible schedule for completion of that original plan -or- source of funding.
Long-distance "high speed" rail is going nowhere in CA without constraints on air travel, especially short-hop flights, that includes taxation for environmental consequences. Nobody flying the Bay Area or Sacramento - L.A. corridor is going to spend 4X as much to spend double the time in transit.
