tmasterpiece, Best quality at best，If future trains could travel in the sea, their design would likely be significantly different from current train designs. They may have a streamlined and aerodynamic shape to reduce drag and increase speed. They may also have advanced waterproofing and buoyancy systems to allow them to float and move through the water. Additionally, they may have advanced propulsion systems such as hydrofoils or submarines to generate the necessary power to move through the water. The train may also have advanced safety features such as collision avoidance systems and advanced life-saving equipment to ensure the safety of the passengers. However, the exact design of the sea-faring train's exterior would depend on the advancements in technology and the needs of the passengers.
