This paper applies an improvement cycle for analysing and enhancing capacity utilisation of an existing timetable. Macro and micro capacity utilisation are defined based on the discrete nature of capacity utilisation and different capacity metrics are analysed. In the category of macro asset utilisation, two methods of CUI and the UIC 406 are compared with each other. A British and a Danish case study are explored for a periodic and a nonperiodic timetable: 1- Freeing up capacity by omitting the train that has the highest capacity consumption (British case study). 2- Adding trains to use the spare capacity (Danish case study). Some suggestions are made to develop meso indices by using the UIC 406 method to decide between the alternatives for adding or removing trains.
