Amtrak equipment travels more car miles per day than other countries' HSR equipment? Hours per day I would believe but miles - I dunno, HSR in Japan, France, etc. rack up a lot more miles per hour than Amtrak's LD trains do. A couple hours per day at those speeds would seem to yield more miles than an Amtrak train does in a day.Actually you are correct in your first sentenance. Amtrak is a success in that with the exception of Japan and China it has a higher car miles per day than any of the systems we like to admire. Even the HSR trains in western Europe have a much lower mileage per day than Amtrak. Most of the LD trains in the east run 24 = 40 hours before ending thei trips and then turn back in about 14 -20 hours back. The western LD trains are even more used as their routes are up to 60 hours long before reversing.. The last I read Amtrak has about 85 - 90% of cars ready for service. Of course some are not in the best repair for dispatch.
