820 miles in 2 1/2 hours is 328 mph. There is no 820 mile train run in the world with that type of speed. Not now but there will be........ever heard of Maglev trains? We gave up on Maglev trains in the 1970's.....Republicans didn't like the threat it presented planes and cars. However, the Germans and Japanese kept doing the research. Flash forward to 2007, the Japanese have opened up a commercial line in Japan and the Germans have opened one from Shanghai's airport that eventually will take passengers to its downtown train station. Maglev trains routinely hit speeds over 300 mph. There are still problems with the technology but its improving quickly. Here's a video clip of a Maglev train: video.google.com See what you can accomplish when you don't have people like your leaders holding us back. You will note that the speeds are in kilometers. Funny how the rest of the world is on the metric system and we aren't. What do Republicans have against the metric system? TGV did hit 357 but with some modifications, and only on a test run. Not hauling passengers across hundreds of miles. The top speed on any regular run is more like 200 mph, and that's instantaneous tops speed not sustained speed over a while run. And most routes have an instantaneous tops speed of either 168mph or 186. Adding the passengers would not be a big deal; its the using of oversized wheels to minimize friction that made the difference. They have to come up with the technology, and they will, that uses the smaller, typical wheels currently in use. Right now in France, TGV's by law are not allowed to go over 250 mph. You see just like here they have conservatives who are afraid of the higher speeds. The highest average speed between terminating stations for any regular service is 250 kph or less than 160 mph over a distance of 750 km (or about 465 miles). en.wikipedia.org. Also its not just a matter of how fast you can get trains to go. Pour enough resources in to the effort and you can get some pretty amazing results. But how much total spending you will need per passenger mile. Think about it Tim......the track right of ways are in place.....that's the most expensive part......buying the land. You should replace the track with seamless track although the Swedish high speeds trains don't require it......those are the fast trains in use on the Boston-DC route and the Vancover, BC -Portland, OR route. However those trains can't go much faster than 125 mph. In any case, the cost will be less than building a new freeway or airport. So what's the big deal? More high speed rail in certain situations probably does make sense but its hard to tell if the only way it ever happens is with massive subsidies. I hope it takes massive, massive subsidies that prevent us from taking on more wars. ;-)
