The first floating passenger train under construction in Seattle!

In the United States, Seattle is currently in full swing. The city already hosts four of the world’s largest floating bridges. Today, she builds the first floating passenger train in the world Presentation of this crazy project.

Local transit agency Sound Transit is working on the construction of the first floating passenger train. The project is expected to be completed with a floating bridge over Lake Washington in 2023.

This project is part of a larger – $3.7 billion – plan to develop a rail line linking Seattle to Bellevue, Washington. The bridge will have to support two pairs of 300-ton trains that will evolve at 90 km / h. The challenge is big.

Sound Transit estimates that there are 50,000 daily passengers. Should an incident occur on the bridge and the train derailed, it could fall off the bridge and sink 60 meters underground. The error is not allowed!

Twenty pontoons will be linked together and anchored to the lake bed with steel cables to ensure the buoyancy of the structure and stabilize the whole in case of strong waves and / or strong wind.
