BBT SE: A European public limited company for the construction of a railway tunnel between Austria and Italy. At the request of the Republics of Austria and Italy and the European Union, BBT SE is planning and building the Brenner Base Tunnel.

The acronym SE stands for Societas Europaea. This is a transnational type of company provided for by European law. BBT SE is 100% publicly owned. Since half of the shareholders are from Austria and half from Italy, this type of company is ideal.

In 1999 the Austrian and Italian Ministers of Transport established a European Economic Interest Grouping (EEIG), known as BBT EEIG. The company was set up to plan the Brenner Base Tunnel. On December 16th, 2004, it became Galleria di Base del Brennero – Brenner Basistunnel BBT SE.
