FREIGHT RAILWAY TRANSPORT: CRITICAL VARIABLES TO IMPROVE THE TRANSPORT APPLIED TO INFRASTRUCTURE COSTS AND ITS ASSOCIATED TRAFFIC FLOW

[EN] The developed societies have as challenge, among others, to achieve a mobility development based on economic models of low carbon and energy efficient, making it accessible to the entire population. In this context, the sustainable mobility seems to meet the economic, social and environmental needs, minimizing their negative impact. There are three factors that are relevant: (1) infrastructures; (2) modes of transport more ecological and safe, and (3) operations and services for passengers and freights. The objective of this research is to provide guidance to investment in sustainable transport infrastructures that are truly useful and effective. In particular we have studied the case of the railway, using the following information: details of the infrastructure; cost of construction (per kilometre); maintenance cost, and life cycle. This information may be relevant to consider their possible business models. The methodology of this research was focused in the detailed analysis of the infrastructure use and maintenance criteria, the market opportunities for freight development and the available data to validate the obtained results from the software tool reached in this work. Our research includes the different following aspects: • Evaluation of the supported traffic by the rail line. • Relevant items to be considered in the rail infrastructure. Defining the track, we can group items in two sets: civil and rail installations. • Rolling stock available. Locomotives and wagons are modelled to introduce the data as convenience for the user. Besides our research includes the development of software, Decision System Tool (DST), for studying the construction and maintenance cost of railway infrastructure. It is developed in a common and open source program, providing the user the interaction with the critical variable of the line. It has been adjusted using the following references: MOM PlanCargorail; EcoTransIT, and Projects funded by Framework Program of EU (NewOpera, Innotrack and Sustrail).Sanz Bobi, JDD.; Martinez Muneta, ML.; Sanz Lopez, M.
