COMSA plays an active role in the development of high speed railway infrastructures both in Spain and abroad.
The route requirements of high-speed train lines result in extremely difficult and technically complex projects.
In 2006 COMSA expanded its business horizons by working on the infrastructures for new routes such as the Asturias link and the Vitoria-Bilbao section.
At the international level COMSA also operates through its subsidiaries in Italy, Australia and Taiwan.
