RESUMENEl texto recoge la polisemia del concepto paisaje, su uso por las distintas disciplinas y su imbricación con otros términos, como los de medio, entorno, identidad, ambiente, carácter, etc., todo lo cual ha conducido a una imprecisión terminológica o a un embrollo conceptual que se manifiestan de forma muy evidente en la legislación, que parece situar los significados del paisaje entre los valores del medio ambiente y los del patrimonio cultural. Sin duda alguna, como concepto cultural que es, el paisaje tiene muchas facetas, pero de cara a la conveniente ordenación del paisaje en el marco de la planificación espacial es urgente convenir los aspectos básicos que lo definen. Palabras clave: terminología de paisaje, paisaje cultural, planificación espacial, legislación española. ABSTRACTThis text makes reference to the polysemy of the concept of landscape, as well as to the use that the different disciplines make of it, and its interdependence with another terms such as environment, scene, identity, ambiance, character, etc.; all this has driven to a lack of precission in the terms or a conceptual mischief that is clearly manifested in the legislation, that seems to settle the meanings ot the concept of landscape between the values of the environment and those of the cultural heritage. Undoubtedly, as a cultural concept, the landscape has many faces but, in order to perform a proper landscape planning in the context of the spatial planning, it proves to be urgent to come to an agreement about the basic aspects that define it.

RESUMENSe plantea en este artículo una crítica acerca de los sentidos de algunos conceptos habituales en el urbanismo y directamente relacionados con la correspondencia entre espacios urbanos e infraestructuras de transporte. Los autores se interesan especialmente por los significados y usos de acepciones tales como conectividad, accesibilidad y movilidad. Abriendo el debate terminológico y elucidando la perspectiva del análisis teórico, esta contribución combina unas notas sobre la movilidad urbana sostenible y el planeamiento orientado por la política de transporte urbano. Palabras clave: conectividad, accesibilidad, movilidad, transporte urbano. ABSTRACTIn this article a critique is laid out about the senses of some habitual concepts in the urbanism and directly related to the correspondence between urban spaces and infrastructures of transport.

This study examines urban collective transport policy in the city planning of three European countries under the Socialist Bloc in the 1950s and 1960s. The main aim is to account for the success of the private car in approaches to urban infrastructure and to understand how this affected tramway system planning. This then leads to a new perspective in understanding the conflict between the adoption of transport vehicles: The diversity of argument in tramway planning has been analysed using official publications, professional literature, and the urban and transport plans of the three case study cities. It results that planning solutions prioritised more national and local conditions, their logic and the singularity of their characteristics over the specific principles related to the ideology of the communist regimes.

This paper offers a conceptual overview of the state of the art relating to the historical interre­lationships between railways and cities from the point of view of town planning, covering the good century and a half that there have been railways in the Iberian Peninsula. It addresses both urban and railway history, reconsidering major issues in this relationship. These are: 1) the tracks of lines as they cross cities and the role they play in urban life, 2) the passenger buildings of stations, seen as a focus of urban centrality, 3) the developing complexity of cities and rail­ways, together with the installation of new road and port infrastructures, and 4) the problems emerging from urban ex­pansion in the final third of the twentieth century, mostly after the restoration of democracy, specifi­cally the question of the limited permeability of rail tracks and the interpretation as a social barrier of the physical barrier thus constituted by the railway. An idea that railways are a problem grew up within this historical interrelationship.
