The objectives of this module are to introduce us to the essential aspects for successfully tackling and guaranteeing the design, project and construction of the different parts that make up a high-speed line. Likewise, we will learn about both the material means and the human resources necessary to deal with the maintenance of the different railway subsystems: infrastructure and track, energy, signalling and telecommunications.
