抄録: There is an increasing trend to consider high speed rail as a vertically separated industry in order to introduce more competition and better interoperability. A first consequence is a standardisation of rolling stock designs and the development of cost optimisation and decision support tools to increase the competitiveness of infrastructure management, which both aim at improving high speed rail services. However, high speed rail is an integrated system and this loss of integrated approach is not optimal from an engineering perspective. Engineering choices were historically guided by the local contexts of each country or region, and the many potential markets should have the opportunity to develop a system that is adapted to their own context. For these reasons, a life cycle cost model is proposed to optimise the choice of high speed rail systems under a given context. This simple yet versatile model highlights the trade-offs between train design, infrastructure design, and operating constraints. It reveals that the manufacturers could consider larger capacity train designs. More importantly, it illustrates that a non-integrated approach such as a vertical separation without coordination leads to significant cost increases. Since higher costs would eventually be borne by the users or by the society, the regulatory authorities of the numerous high speed rail projects that are being implemented must not only coordinate the stakeholders but also ensure that their propositions and choices have a positive impact with adequate decision support tools.
