Abstract: Availability and capacity along with functionality are the major keys for success of the division infrastructure of the Swiss Federal Railways SBB. With the installation course of the "value of time" VoT a meaningful and objective instrument is creates, in order to quantify the availability and the capacity for the calculation of the Life Cycle Cost. There are two kinds of VoT: - Planned non-availability (investments-projects or maintenance-work) and therefore reduction of capacity ("value of capacity") - Unplanned non-availability, breakdown and work to restore service ("value of availability") This goes beyond the usual purely qualitative view added to the quantitative hard-facts of investment cost. With the definition of a value for one hour of downtime of one track a comprehensible comparison is enabled in a simple an practicable way. As base for decisions in the product management / systems engineering and with innovations projects these values supply necessary assurance. The used values in CHF are verified constantly on the basis examples. For specific parts of the network adapted costs can be used, in order to illustrate e.g. a particularly high density of traffic or to justify the specific us of high performance systems according to the density.
