The organization of freight train movement is subordinated to the adopted production scheme in operation. If the production scheme is not considered plausibly, the management of freight train movement is “helpless” in providing a service of good quality and no improvements on the performance of railway freight system could be expected. This paper concentrates on analyzing freight train movement, and explores the behaviour of formation yards in terms of a network. Included in this paper are a brief historical review of the adopted production schemes and a discussion of the evaluation and amelioration of the current production scheme of freight train movement of the railway freight operator under study, “Comboios de Portugal” (CP). A new production scheme is also discussed. Validations of the benefits of the new production scheme by a comparison with the current production scheme of CP through aggregate measures of some of the yard subsystems’ performance are also provided. A simulation modelling experiment is conducted by using an event simulation language. A simulation modelling methodology for analysing freight train movement in railway network is developed. The simulation model replicates the performance of railway freight system so that production schemes can be analyzed, evaluated and improved.
