东京名古屋磁悬浮工费再涨，2035年开通仍未定

Core Viewpoint - The total construction cost of the Maglev Central Shinkansen has significantly increased from the initial estimate of 5.52 trillion yen to 11 trillion yen, reflecting rising material prices and construction difficulties [2][5]. Group 1: Cost Increases - The revised total construction cost is now estimated at 11 trillion yen, an increase of approximately 4 trillion yen from the previous estimate of 7.04 trillion yen [2]. - The rise in costs is attributed to a 2.3 trillion yen impact from higher prices, including 1.3 trillion yen due to increased prices of construction materials like steel and concrete, as well as labor costs [5]. - An additional 1 trillion yen has been included to address potential future price increases, while 1.2 trillion yen is allocated for dealing with construction challenges due to unexpectedly fragile geological conditions [5]. Group 2: Funding and Financial Strategy - JR Tokai plans to cover the funding shortfall through operating cash flow, company bonds, and loans, with the government having already invested 3 trillion yen [4]. - An estimated 2.4 trillion yen is needed to cover construction costs while maintaining "sound operations and stable dividends," assuming the opening date is set for 2035, although this is still tentative [4]. - The president of JR Tokai, Shunsuke Niwa, indicated that the excavation work for the Shizuoka section of the Southern Alps tunnel has not yet started, making accurate predictions difficult [4].
