Lines R2 and R4 to be taken underground in L´Hospitalet de Llobregat (Barcelona)

RN TÁRYET, a company of the TPF Group, is a partner in the joint venture that has been awarded a contract by ADIF to perform the preliminary and detailed design of the works that will put Line R2 and Line R4 underground in L´Hospitalet de Llobregat (Barcelona

The works to be designed are challenging in terms of urban planning, due to the constraints associated with sending the railway lines underground, and in terms of railway functionality in this major commuter hub for Barcelona.

The railway arrangement provides a flexible operating model for the lines running across Barcelona, forming a railway “hinge” that allows for all possible routes, at different levels, with a third track for regional trains.In addition, the project includes a station in La Torrasa for intermodal exchange between both commuter lines and the Metro lines.

The geometric layout, tunnels and structures, as well as the provisional situations to be planned in order to select the final solution, are key elements of the project on account of their complexity and the shortage of space.
