investigations on cost and benefit have been made, released 2007 and 2012. These plans were shelved in 2013, although still open for restart in a decade or so. There are ongoing and coming projects for high-speed upgrades on the closest 50–100 km from Oslo on each of these lines (except direction Stockholm). They have good potential for regional trains. Upgrade and new construction to high-speed standard have to some extent already taken place like for Gardermobanen. The time plan is to have 200 km/h or more from Oslo to Porsgrunn (partially slower), to Hamar and to Råde east of Moss around 2020–2025, and to Halden and Hønefoss later, maybe 2030. The regional projects near Oslo have higher priority than the long-distance projects. They are also preconditions for the long-distance projects, since they will be used by long-distance trains. Poland Warsaw to Poznań and Wrocław via Łódź (planning postponed in 2011) Warszawa-Toruń-Gdańsk high-speed railway Central Rail Line was designed for speeds of up to 250 km/h. 200 km/h is used in commercial service, however higher speeds are planned later. Portugal Portugal's Prime Minister António Costa announced in September 2022 a $4.7 billion passenger rail line running round 300km (185 miles) from Lisbon-Oriente to Porto-Campanhã, cutting travel time by over 50% to 75 minutes non-stop, and 105 minutes with stops in Leiria, Coimbra and Aveiro. A future second phase will include another 150km (100 miles) to Porto Airport, Braga, Valença, and a connection to Vigo in Spain. Lisbon–Porto high-speed rail line (proposed in 2020) Romania In 2021, the European Commission approved 3.9 billion euros for rail in Romania's National Recovery and Resilience Plan, which will modernize railways, rolling stock, and signaling systems. A 120 million euro feasibility study for a high-speed line between Constanta through Bucharest to the Hungarian border was begun in 2022 and expected to be completed by 2026. Among the possible options are a fully high-speed 590 km route be through Sibiu, Cluj, and Oradea which could cost 17 billion euros; another possibility is a hybrid line with some sections at 200 km/h, and some sections at 160 km/h. Russia Since 1980s, the several proposals of high-speed network were made. Vladimir Putin announced plans to build a 770 km high-speed rail line that would connect Kazan and Moscow at the Economic Forum at St. Petersburg in 2013. Plans for the railroad estimate that it will be the first true
