28 June, 2026

Inse Rail has been awarded the contract for the “Technical Assistance for the Monitoring and Supervision of the Rail Replacement Works on the Infiesto–Arriondas Section, between KP 361+700 and KP 383+344, of Line 770: Oviedo–Santander,” promoted by ADIF.

The project forms part of ADIF’s ongoing railway infrastructure renewal and modernization program for the conventional rail network, aimed at improving the reliability, safety, and operational quality of rail services along this section of northern Spain’s railway network.

These services comprise technical oversight, quality control, schedule monitoring, and support for the coordination of construction activities within an operational railway environment.

The renewal of this section will enhance operating conditions, passenger comfort, and service reliability, while also optimizing the maintenance requirements of the railway infrastructure.

With this award, Inse Rail further strengthens its position in the field of railway engineering and technical assistance, reinforcing its participation in strategic projects for the modernization and improvement of the railway network managed by ADIF.
