The work consisted of constructing a double track between the San Lorentzo and University halts, on the Bilbao-Donostia line of Basque train operator Eusko Tren.

All the execution was planned in accordance with the need to keep the line open to railway traffic at all times.

The extension of the existing levelled area in order to lay the second track necessitated the widening of an existing flyover, and protection of the excavation in the cutting with mesh and bolts on one side and multiple retaining walls of micropiles anchored on the other.

The new tracks are composed of UIC54 rails and mono-block sleepers, also including the supply and erection of a type A switch and a type B crossover.
