Helsinki–Tallinn Tunnel

April 12, 2024

The Helsinki–Tallinn Tunnel (also known as FinEst tunnel[1][2]) is a proposed undersea tunnel that would span the Gulf of Finland and connect the Finnish and Estonian capitals by train.[3] The tunnel's length would depend upon the route taken: the shortest distance across would have a submarine length of 80 kilometres (50 mi), which would make it longer than the current longest railway tunnel in the world, the 57 km (40 mi) Gotthard Base Tunnel.[4][5][6] It has been estimated that the tunnel, if constructed, will cost €9–13 billion. It may open in the 2030s.[7][8][9] The European Union has approved €3.1 million in funding for feasibility studies.[10] A pre-feasibility study from 2015 proposed a 250 km/h top speed.[11][12]

On 8 February 2024, Finnish Minister of Transport and Communications Lulu Ranne told Estonian daily Postimees that the tunnel is "unrealistic" and not on the agenda of the government, with the project remaining on hold unless further funding was provided by the European Union.[13]

Background edit

Helsinki and Tallinn are separated by the Gulf of Finland. The distance between the cities is about 80 kilometres (50 mi). Travel between the capitals is currently mainly by ferry and fast passenger boat, travel time varying from 1 hour 40 minutes (fast summer ferries operating from April to October) to three and a half hours (normal ferries operating year round), but most ferries now take two hours. Some eight million journeys are made by ferry each year, including both leisure cruises and scheduled commuter services. Overland travel between Helsinki and Tallinn requires an 800-kilometre (500 mi) journey through Russia.[14] There are also around 300,000 air trips done per year between the cities.

Project status edit

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.[15] 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.[16]

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.[17]

The results of the preparatory survey were released in February 2015.[18] 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.[19]

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.[20] In June 2016, the EU granted €1 million for the study which is expected to be ready in early 2018.[21]

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.[22]

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.[23]

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.[24] The deal consists of memorandum of understanding for a 15 billion euros financial deal to fund 4 stations, the tunnel and the trains.

On 26 April 2021 the governments of Estonia and Finland signed a Memorandum of Understanding (MoU) on mutual cooperation in the transport sector. The MoU included the undertaking that both countries would cooperate in large-scale transport projects, such as the Helsinki-Tallinn railway tunnel, but it did not commit any of the parties to any particular project. The MoU will remain in force until 2030.[25][26]

Cost and benefits edit

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 (for comparison, the Rail Baltica project has received 85 per cent of its funding from the EU).[27]

 
The Øresund Bridge 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 (the Øresund Region has been offered as an example), 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.[28]

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.[29]

The investment for the tunnel was estimated to pay itself back in about 17 years. Suggested passenger prices were 50 euros one-way and 2500 euros for unlimited annual ticket.[30]

Technical details edit

Railways in Finland and Estonia use 1,524 mm (5 ft) track gauge. The Helsinki–Tallinn tunnel would according to current planning use Standard gauge 1,435 mm (4 ft 8+1⁄2 in) 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 (apart from the Rail Baltica track) 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 (Riihimäki and Tampere have been suggested) 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.[27][31]
