World’s steepest railway line 世界上最陡峭的缆索铁路 本集内容 World’s steepest railway line 世界上最陡峭的缆索铁路 学习要点 有关“heights 高度”的词汇 边看边答 What dangers did the workers have to deal with on this project? Up here, 13 hundred metres above sea level, is not a view for the faint-hearted, and transporting people up this steep Swiss mountainside is not without its challenges. Two years behind schedule, it's taken 14 years of building with a price tag of 53 million dollars. But the Swiss are convinced the new funicular on the world's steepest line is worth it. Reinhold Boiger, Engineer “To construct a tunnel with a 110% gradient has rarely been done before. All the workers have to secure themselves. Sometimes they have to work hanging in the ropes. We have to be very careful with the material. If you drop something it falls all the way down, and what’s even more dangerous - if you drop something, it can fall on the head of a worker further below.” If the breathtaking climb itself doesn't leave you weak at the knees, then standing upright in the carriages shouldn't be a problem either. They’ve been uniquely designed to allow the floors to adjust with the gradient as it travels. Each of the carriages can carry 34 people, at a speed of ten metres per second, meaning the climb or descent lasts no longer than four minutes. |
