Finnish Entrepreneur Proposes Helsinki-Tallinn Sonicloop ({{commentsTotal}})

Finnish businessman Niko Stahlberg unveiled an idea at the Tallinn University of Technology's ConnectBaltica conference to connect Tallinn and Helsinki via a supersonic train capable of speeds of up to 1,600 kilometers per hour.

Stahlberg told Eesti Päevaleht that he has an international team in place and is in negotiations with investors to build a prototype to be tested in a lake.

The train would travel through a submerged tunnel that would be floated when the train nears its destinations. The propulsion side of the system would be similar to how railgun technology works.

Stahlberg said he hopes to finish the project in a decade and estimates the costs at 300 to 500 million euros.
