CNN News:隧道穿越阿尔卑斯山脉 缩短旅行时间

Which of these mountains is the shortest? Mont Blanc, Denali, K2, or Mount Kilimanjaro. At less than 16,000 feet tall, Mont Blanc is the shortest on this list and it's the tallest mountain in Europe.
Mont Blanc is located in the Alps and the Swiss part of the mountain chain is where our next story takes place as engineers there are putting the finishing touches on a new high speed, high capacity railway. This is part of a project to establish better and faster rail links in the region. The mountains have always been a major obstacle to that but the scenari-based tunnel cuts right through them. It's nine and a half miles long. It will join the remaining mountain section separating northern Europe and northern Italy and it will be a complement to the Gotthard based tunnel which opened in 2016.

That passageway is 35 miles long. It took 2,500 people and $11 billion to build and though they don't offer the same astounding views as the old mountain route, these tunnels are flatter and less curved which allows heavier freight trains and more of them to travel through the Swiss Alps.
In fact the biggest benefit to these projects will be the freight companies who can now send more goods and commodities in less time through the Alps.
And as far as travelers are concerned, the total trip time between Zurich, Switzerland and Milan, Italy will be shortened from four hours to two and a half hours.
