The Murcia-Caravaca de la Cruz railway, which today serves as the basis of this Greenway, was built with public funds at a time when private enterprise saw little profit in railways. The first route proposed was to run between the towns of Fortuna and Caravaca de la Cruz. But, before work had begun, the final section was altered in order to connect with the station at Alguazas which was on a direct line to the provincial capital, Murcia, with a view to making the line more profitable. Work eventually started in 1925 and was remarkable for the multitude of bridges and viaducts along its route.

Although the works were completed in 1931, the line was actually opened two years later, on May 28, 1933. From the outset its success could only be described as modest, but later, when it had to compete with the private car and road transport, the situation became practically untenable. In 1964 the passenger trains, formerly pulled by steam locomotives, were converted to railcar operation which was more economical, faster, and more reliable. But this did little to improve the railway’s situation which was worsening with every passing day. Finally, on April 15, 1971 all services between Alguazas and Caravaca were withdrawn and shortly after the rails and sleepers were removed. Only in the section between Alguazas (where the line connected with the Chinchilla-Cartagena line) and the terminus at Murcia-Zaraiche were the tracks left in place. This section stayed open for the occasional goods train until the early 90s. Today the tracks are still there, but they are overgrown and undisturbed by trains of any kind.
