jones_supa writes A train link between Finland and continental Europe could become a reality 15 or 20 years from now. A study carried out by Sweco Consulting recommends moving ahead with negotiations on building a railway tunnel between the capital cities Helsinki and Tallinn. According to a preliminary report out Wednesday, an undersea link would shorten the travel time between the two capitals from the current minimum 90 minutes by ship to around 30 minutes by rail. Estimated ticket cost is about 40 euros. The study, commissioned by the two cities, estimates that the undersea route could be completed after 2030 and would cost somewhere between 9 and 13 billion euros.
