Given the increasing importance of railways in the global context, either as a means of transport or as a tourist product, this paper aims to provide an alternative to the closure of the Aranjuez-Cuenca-Utiel railway in Spain. From the point of view of sustainable tourism, it is intended to highlight the role of this railway as a backbone of territorial socioeconomic development. The recovery and enhancement of the Portuguese Duero line is presented as an example for the future of the Cuenca's Province railway. [ABSTRACT FROM AUTHOR]
