Urban Transport

Subway design has evolved from mostly underground lines built using the NATM or TBM methods to above-ground systems whose implementation is more complex from an urban development point of view, but which is clearly less expensive.

We have been protagonists of this evolution through our projects, from the first metro lines in Spain and Portugal, where we have participated in most of the systems, acquiring experience in tunnels that we later applied to other countries such as Mexico, Brazil and Panama. The experience in systems integration that we acquired from the Line 9 Barcelona metro project was also highly valuable, which has since been extended to practically all of our projects.

We currently cover all the technical challenges involved in the construction and operation of a metro system:

• Tunnels in an urban environment both in NATM and TBM or cut-and-cover-tunnel.
• Light or heavy rail systems implemented with elevated structures.
• Stations and transport hubs that must be integrated into urban environments and serve as the center of an increasingly changing type of mobility within the city.
• More than 30 depots and workshops. At Sener, we believe that operation and maintenance are the beginning and end of the system’s requirements, while depots are at its heart.
• More automated, complex railways systems that also serve as a basis for reliability and safety.
• More than 750 km of subway lines in 25 cities in all phases a project’s life cycle.

Some of our most relevant underground metro projects include:

• Panama Line 1 in Panama.
• Sao Paulo Line 6 in Brazil.
• Barcelona Line 9 in Spain.
• Riyadh Metro in Saudi Arabia.
• Oran Metro in Algeria.

Some of our most relevant above-ground projects include:

• Guadalajara in Mexico.
• Doha Red Line South in Qatar.
