Helsinki–Tallinn Tunnel


The Helsinki to Tallinn Tunnel, also called the Talsinki tunnel is a proposed rail undersea tunnel that would span the Gulf of Finland and connect the Finnish and Estonian capitals - a common region referred to as Talsinki. The tunnel's length would depend upon the route taken; the shortest distance across would have a submarine length of, making it the longest undersea tunnel in the world. The tunnel, if constructed, is estimated to cost €9–13 billion and would open sometime after 2030. The European Union has approved €3.1 million in funding for feasibility studies.

Background

and Tallinn are separated by the Gulf of Finland. The distance between the cities is about. The region is commonly referred to as Talsinki. Travel between the capitals is currently mainly by ferry and fast passenger boat, travel time varying from 1 hour 40 minutes to three and a half hours, but most ferries now take two hours per trip. Some eight million trips are made by ferry each year, including both leisure cruises and scheduled commuter service. Overland travel between Helsinki and Tallinn requires an journey through Russia. There are also around 300,000 air trips done per year between the cities.

Project status

Both cities have promised €100,000 for preparatory studies, though the relevant ministries of each country have refused to grant any funding. An application is now planned to the EU to gain the additional funds needed for a comprehensive survey, estimated to cost between €500,000 and €800,000. On 13 January 2009, newspaper reports suggested the application to the EU, through the Interreg programme, for comprehensive surveys had been denied. An expert at the City of Helsinki's International Affairs department suggested this may have been because of political tension within Estonia, between the national administration and the City of Tallinn, both controlled by rival political groups. Nevertheless, both cities are said to be considering funding the surveys themselves.
On 2 April 2014, it was announced that a €100,000 preparatory survey named TalsinkiFix will assess whether a more comprehensive profitability calculation should be done. The European Union will cover 85 per cent of the survey costs and the cities of Helsinki and Tallinn and the Harju County will pay the rest. This is the first official survey about the tunnel.
The results of the preparatory survey were released in February 2015. The cost of the tunnel was estimated to be €9–13 billion and the tunnel could open at earliest after 2030. The survey recommended the tunnel to be built for railway connections only with the traveling time between Helsinki and Tallinn being half an hour by train.
On 4 January 2016, it was announced that the transport ministers of Finland and Estonia as well as the leadership of the cities of Helsinki and Tallinn will sign a memorandum on traffic cooperation between the two countries, including a further study to examine the feasibility of the tunnel. This study is the first to be conducted on the state level and will focus on the tunnel's socio-economical effects and geological analysis. Finland and Estonia are asking financial support from the EU for the study. In June 2016, the EU granted €1 million for the study which is expected to be ready in early 2018.
In August 2016 a two-year study was launched by the Helsinki-Uusimaa Regional Council. Other partners in the study are the government of Harju County, the cities of Helsinki and Tallinn, the Finnish Transport Agency and the Estonian Ministry of Transport and Communications. The project is headed by Kari Ruohonen, the former director general of the Finnish Transport Agency.
In February 2017 two consortia were commissioned to study aspects of the project. One will study passenger and freight volumes and do a cost-benefit analysis. The other will study the technical aspects of the project.
In March 2019 a similar project by Peter Vesterbacka has moved forward. Vesterbacka has made a tentative deal with Chinese investment company called Touchstone Capital Partners. The deal consists of memorandum of understanding for a 15 billion euros financial deal to fund 4 stations, the tunnel and the trains.

Cost and benefits

The cost of the tunnel connection has been tentatively estimated to be €9–13 billion. This includes €3 billion for the tunnel excavation, €2–3 billion for infrastructure and security systems, over €1 billion for rolling stock and other equipment and €1–3 billion risk marginal for unexpected situations. The project is estimated to be financially feasible if the European Union covers at least 40 per cent of the cost, the rest being shared by Finland and Estonia and the two capital cities.
integrates the cities of Copenhagen and Malmö to a single economic area. The Helsinki–Tallinn tunnel is expected to have a similar effect.
The economic benefits would be significant, both in terms of increased connections and economic integration between the two cities, but also in a wider context of convenient passenger train connections between Southern Finland and the Baltic states, and a fixed link for freight from across Finland on to the Rail Baltica, thus providing a rail freight connection with the rest of Europe. An estimated 12.5 million annual passengers would use the tunnel.
Geopolitically, the tunnel would connect two close but separated parts of the European Union in an environmentally friendly way, removing the need to use sea or air transport, or to travel through Russia. The Helsinki–Tallinn connection is part of the EU's TEN-T network's North Sea–Baltic corridor. The ports of Helsinki and Tallinn have previously received EU funding to improve transport conditions between the two cities.

Technical details

and Estonia use track gauge. The Helsinki–Tallinn tunnel would according to current planning use European gauge tracks to connect directly to Rail Baltica which uses the same gauge. This means trains traveling through the tunnel from Tallinn to Helsinki could not continue onwards to other Finnish destinations and vice versa without new tracks being built or the use of a variable gauge system. Tentative plans have been made to build separate freight stations in Southern Finland which would make it possible to load trains outside Helsinki for transportation through the tunnel. Tampere and Helsinki Airport could also host passenger terminals for trains heading to Tallinn and onwards to Central Europe.
