Inse Rail’s Design for ADIF High Speed’s New Madrid Maintenance Depot Moves into the Construction Phase

28 June, 2026

The detailed design developed by Inse Rail for ADIF High Speed’s new rolling stock maintenance depot at the Madrid South maintenance base has reached a new milestone with the launch of the construction tender, marking the transition from the engineering phase to project delivery for a strategic railway infrastructure.

With a tender budget of €90.4 million, the project will provide ADIF High Speed with a state-of-the-art maintenance facility for locomotives, track recording trains and other auxiliary railway vehicles, increasing maintenance capacity and improving the efficiency of railway infrastructure operations.

As the company responsible for the detailed design, Inse Rail delivered the engineering required to define a highly complex maintenance facility, integrating civil engineering, railway track systems, electrification, industrial facilities, architecture, site development and railway systems. The project includes a maintenance building equipped with internal tracks, inspection pits, overhead cranes, specialist workshops, logistics areas and technical facilities, together with new track yards, connections to both the conventional and high-speed rail networks, electrification, signalling and telecommunications systems, railway equipment, as well as drainage networks and auxiliary services.

The publication of the construction tender represents the completion of the engineering stage and the beginning of the execution phase of a project that will strengthen ADIF High Speed’s maintenance capabilities while enhancing the availability and reliability of the railway vehicles used to maintain Spain’s rail network.

With this project, Inse Rail continues to strengthen its position as a trusted partner in the delivery of complex railway engineering projects, contributing to the modernisation, sustainability and operational efficiency of Spain’s railway infrastructure.
