Although I agree with you that West Coast and East Coast lines should be built (West Coast first, as a test case), I think that you’re making the lines longer than they ought to be to start with.
High-speed rail (HSR) really comes into its own for trip lengths of about 100-400 miles (currently – as fuel costs rise, the upper limit grows):[ul]
[li]Below 100 miles, the time savings of HSR don’t easily compete with the lower cost and flexibility of other local transportation (regular commuter rail, subways, light rail, buses, and the omnipresent automobile). [Although some <100mi intermediate trips like San Francisco-San Jose would benefit from HSR, they aren’t a sufficient driving force for implementation of HSR].[/li][li]Above ~400 miles (between “viable revenue points”), air travel starts to win on time alone. This is why no serious plans are made for US transcontinental rail travel as a primary source of revenue. [The same is true in Europe: although Spain’s HSR network will soon connect to those of France – and hence Germany – it’s not because they want to capture that elusive Seville-Berlin market. Each “local” network stands on its own merits, and that’s how it should be in the USA.][/li][/ul]West Coast Line:
San Francisco and LA are just about the ideal “city pair” for HSR in the US. The current Bay Area - Greater LA air corridor is one of the busiest in the nation, and SFO is one of the most weather-delay-plagued airports. Current plans to expand SFO and LAX run of the order of ~$10 billion apiece. Experience in Europe has shown that up to 50% of the point-to-point air traffic on HSR-amenable corridors can be taken over by rail, which means that SFO/LAX airport expansion may not even be necessary if HSR is put in. Since the California HSR project is estimated to cost ~$40 billion in total, half of that money should be available just by not expanding those two airports.
An important factor in choosing the SF Bay Area <-> LA Basin route for the USA’s first true HSR is that, although local rail throughout California is experiencing great success (BART and Caltrain in the SF Bay Area, MTA and Metrolink in the LA basin, and the Trolley and the COASTER in San Diego are all doing very well, as are Amtrak’s Capitol Corridor and San Diegan services), there is currently no longer-distance HSR to link them together. The success of the local rail lines does show that even Californians will renounce their cars if a suitable rail alternative exists.
Although there are good cases to be made for “SF-LA” and “Sacramento-LA” HSR routes as shown here, it’s much harder to make the case for HSR north of Sacramento. The next “HSR-worthy” city would be Portland OR (637 track miles North of Sac), which would also involve a crossing of the Cascades – which would be very expensive. There may be a case for HSR in the Vancouver - Seattle - Portland - (Eugene/Springfield) axis, but the density on that route would be much less than in the case of California HSR. IMHO, put it on the back burner.
East Coast Line:
Although the Northeast Corridor (NEC) has the densest linear population in the US, and a proven track record (
) of rail usage, there are a few reasons why, IMHO, it should not be the first true HSR in the US:[ul]
[li]It already has the Acela Express service, which covers the 225 miles between Washington DC and New York City in 2hours 45 minutes (i.e. ~82mph average). How much faster could one realistically make HSR over that distance, for a given number of billions of dollars?[/li][li]Because the NEC is so built-up over almost its entire length, acquisition of any further land for the railroad is very expensive. [Of course, land is also expensive in SF and LA, but the land between DC and NYC is much more expensive than in California’s Central Valley.][/li][li]The NEC runs through several states, so (as Zebra found), even the Acela Express stops several times between DC and NYC (the fewest number of intermediate stops that I see in the schedule is four). In California, it would be quite acceptable for some trains to be SF-LA nonstop (or at least San Jose-LA nonstop), since California has no intermediate stops equivalent to Baltimore or Philadelphia.[/ul][/li]
DC-Atlanta is 634 track miles, which is currently considerably beyond the range for which HSR competes well with air travel. There’s Charlotte enroute of course, but it’s hard to see that this portion of an HSR network would be justified under current conditions.
Conclusion: FUND and BUILD California HSR ASAP, PLAN for the others. (IMHO)
