Adif AV calls for tenders for ultrasonic auscultation and profiling of high-speed track equipment

Adif has awarded contracts worth a total of €7.2 million for ultrasonic inspection and rail turnout profiling across Spain’s high-speed rail network. The initiative aims to reinforce preventive maintenance, extend the lifespan of track components, and enhance reliability and passenger comfort.

The €5.2 million ultrasonic inspection contract will detect internal flaws in turnouts, crossovers, and expansion devices using high-resolution ultrasonic equipment and GPS-based positioning. The data gathered will inform future maintenance programmes and ensure infrastructure reliability on standard-gauge lines already in operation.

Meanwhile, the €2 million profiling contract will optimise wheel–rail interaction on turnouts along high-speed lines under construction, preparing them for entry into service. Works will take place on sections including Murcia–Almería, Talayuela–Plasencia, and the Antequera–Granada high-speed route, among others.

Through this investment, Adif continues to advance the development of a safer, more sustainable high-speed network, contributing to the UN Sustainable Development Goal 9 on resilient, reliable, and high-quality infrastructure.
