Lifespan of Main Transport Assets

The lifespan of a transport asset is the approximate number of years in which it is expected to perform under normal operating conditions while receiving regular maintenance. Among the major transport assets, the automobile is having the shortest lifespan in the range of 8 to 10 years depending on the level of usage and the operating environment. Rail lines can last for decades, if not a century and a half (depending on the construction materials used), but require a constant and capital intensive maintenance. Transport investments must thus look closely on the expected lifespan of an infrastructure to insure a proper amortization.
