\r\nThe 150km line from J\u00e4rna near S\u00f6dert\u00e4lje to Linkoping will form the initial phase of a Y-shaped network which will ultimately link the Stockholm region with J\u00f6nk\u00f6ping, Gothenburg, and Malm\u00f6. The 320km\/h line is expected to reduce the Stockholm - Linkoping journey time from 1h 39min to around an hour and provide additional capacity for freight and regional passenger traffic on the Western Main Line.\r\nThe project will involve the construction of 27 tunnels totalling 25km, 126 bridges and 29 overpasses, and new stations at Link\u00f6ping, Norrk\u00f6ping, Skavsta Airport, and Vagnh\u00e4rad. Nyk\u00f6ping will also be rebuilt and modernised.\r\nTrafikverket says it expects to hold briefings for prospective bidders later this month. Construction will be divided into 15 packages worth SKr 4-5bn ($US 470-580m) each with the aim of attracting participation from overseas companies with experience in the high-speed sector.\r\nPreparatory works are expected to begin next year with major construction due to begin in 2019 or 2020. Commissioning is scheduled for 2028.
