How about southern California? I’m pretty sure the population density is closer to what is typical for western Europe (that of the whole state is similar to Spain’s). LA to San Francisco is a similar distance as London to Glasgow, which manages travel times well below what you could hope to drive it in, without a modern dedicatted high-speed line (see TheLoadedDog above)

Southern California’s large population growth spurts have occurred in the age of the automobile, and the region is extremely spread-out, with most trips not taking place between defined city centers. The notable intercity rail success in SoCal is Amtrak’s Pacific Surfliner service between San Diego and Los Angeles (with some trains through to Santa Barbara), mentioned by guizot above. It’s the second most-used intercity route in the US after the (Boston-Washington) Northeast Corridor, with 2.5 million riders in FY2005. Metrolink (LA-area commuter rail) is also quite successful; although it has nowhere near the ridership of NYC or Chicago systems, it’s still fairly new.
In Northern California, geography and historical settlement patterns have made growth less sprawled than in SoCal, at least until the recent explosion of SF Bay Area housing prices brought the (cheaper, but more distant) Central Valley into the Bay Area’s commuter domain. So, for instance, Amtrak’s Capitol Corridor service between San Jose and Sacramento (some trains continuing to Auburn in the Sierra Nevada foothills) is the third most-used intercity route in the US, with 1.3 million riders in FY2005.
[Personal example: I live in the Silicon Valley, not far from San Jose, and frequently do consulting work at the University of California at Davis, near Sacramento. The distance is about 105 miles each way, which is a minimum of 2 hours and usually more like 3 with traffic. The train does it in about 2hrs 40min, and has a good on-time record. The one-way ticket is $23; the monthly pass for that trip would be $432 (I don’t make the trip anything like frequently enough to make the pass worthwhile, but there are many daily Bay Area <-> Sacramento commuters for whom it is worthwhile). The train cars are modern and bi-level (good because the views are much better than from the freeway), there’s a lounge / snack car (a couple of beers taster mighty good after a hard days’ work), 120V outlets and tables for laptops, and often a WiFi car. Really, taking the train is a no-brainer for me.]
Still in the Bay Area, the route taken by Caltrain between San Francisco and San Jose (and beyond) is old enough – dating back to 1863 – that most of the population of the SF Peninsula grew along the route, so it’s always had a built-in ridership. It’s unusual among US “commuter” lines in that, with the explosive growth of San Jose and Silicon Valley, both ends of the route are now “real” destinations fore both living and working. Thus, although San Francisco was originally the destination for most morning trains and origin for most evening trains, service is now much more symmetrical and it really fits the “intercity” rather than the “commuter” profile. Ridership is down slightly from the Silicon Valley “boom years” around 2000, but it’s a very important component of travel on the SF peninsula.
[There’s also ACE between Stockton and San Jose – at 86 miles, more “intercity” than “commuter”, but there are only 4 trains per weekday in each direction. So, although it’s successful on its own terms and worth it for the passengers (cheaper than – and time-competitive with – driving), it doesn’t make much of a dent in traffic on that commute route.]
As far as high-speed train service between SF and LA is concerned, that’s definitely a possibilty for the future since the air corridor is already heavily overburdened. The California High Speed Rail Authority plan is to run between downtown SF to downtown LA in 2.5 hours, with several suburban stops at either end to satisfy Exapno Mapcase’s objection. A spur to Sacramento in the North, and continuation to San Diego in the South, would link all of California’s main population centers. The trains would be TGV-style (not Maglev or other “exotic”), and total cost (2004 estimate) would be over $30 billion. Expensive, but not impossible.
[Currently, rail between the SF Bay Area and LA is either >12 hours and scenic (but very likely to be late) or >9 hours and boring (including a >2hr bus ride from Bakersfield to LA). Needless to say, neither of the current options take too many people out of their cars or away from airplanes.
