The objective of the project “Capacity Management” (Capman) was to produce a common methodology to assess the capacity of railway infrastructure.
A first phase of the project aimed at clarification of wording and definitions related to railway infrastructure capacity and to work out a methodology to assess this capacity. In the year 2002 (phase 2) the methodology was tested on over 5.000 km of different line sections across the European networks. It was written down in the UIC leaflet 406 “Capacity” as a recommendation for capacity analysis.
CAPMAN 3 looked deeper into the use of the methodology to be in a position to give recommendations for values such as infrastructure occupation and to get a deeper knowledge of the connection between the level of infrastructure occupation and punctuality. The objective was to better understand, how far it is possible to use congested line sections with a high level of infrastructure occupation.
Simulations have been carried out by six Infrastructure Managers (IM’s). Short outlines of the results of the different simulations are given in the summary report of CAPMAN 3. An infrastructure occupation of 80 % in a peak period seems to be acceptable as one major general conclusion of the project.
