The life-time primary energy savings are higher for high speed trains (104 GJ) compared to average passenger trains with 83 GJ. This results from the higher life- time performance of the high speed trains.

Normal passenger trains have a lower annual and daily performance, but in some cases a higher life-time. The long term average age of Amtrak vehicles in the U.S. is about 13 years for locomotives and 21 years for rail cars ([BTS 2001]). A realistic esti- mate of up to 30 years life-time for locomotives and about 40 years for rail cars can be concluded from this data as well. An allocation of the annual Amtrak train km to the number of locomotives available for service results in an annual performance of over 200’000km and thus over 6 million km life-time performance ([BTS 2001]). Railway as- sociations in state a life-time performance of about 8’000’000 km for the most common locomotives [EFH 2002], while [INFRAS 1999a] even uses a value of 9.6 Mio. km. The life-time performance of long distance passenger trains seems to be higher in Europe due to a busier railway system. Since passenger rail transport is most important in Europe a conservative European value of 8’000’000 km for the life-time performance is used for exemplification.
