How do engineers construct a modern elevated railway across hundreds of kilometers of African savannah, wildlife corridors, and challenging terrain — and complete it in just three years?
工程师们是如何在仅仅三年的时间内,穿过数百公里的非洲大草原、野生动物廊道和复杂地形,建成一条现代化的架空铁路的?

In this documentary, discover how China helped build Kenya’s Standard Gauge Railway, a massive 472-kilometer rail corridor connecting the port city of Mombasa to the capital Nairobi. The project represents one of the largest and most advanced railway infrastructure developments ever completed in Africa.
在本部纪录片中,我们将带您探索中国如何助力肯尼亚建设标轨铁路(SGR)——这是一条连接港口城市蒙巴萨与首都内罗毕、全长 472 公里的巨型铁路走廊。该项目是非洲历史上规模最大、技术最先进的铁路基础设施开发项目之一。

From large-scale earthworks and deep foundation piling to the construction of thousands of concrete bridge piers and elevated viaduct sections, you’ll see how engineers lifted long stretches of the railway above rivers, floodplains, and wildlife migration routes. Massive precast concrete beams, modern track-laying systems, and precision rail welding allowed the railway to be assembled rapidly across the landscape.
从大规模土方工程、深基坑桩基施工,到数千个混凝土桥墩和高架引桥的修筑,您将见证工程师们如何将长距离铁路架设在河流、泛滥平原和野生动物迁徙路线之上。通过使用大型预制混凝土梁、现代化的铺轨系统以及精密的长轨焊接技术,这条铁路得以在广袤的大地上迅速合龙。

Follow the construction journey as this railway cuts across Kenya’s vast plains — passing through national parks, remote grasslands, and rugged terrain where traditional rail construction would be far more difficult.
我们将跟随建设者的足迹,看这条铁路如何横穿肯尼亚的万顷平原——穿越国家公园、偏远草场以及传统铁路建设极难攻克的崎岖地形。

Inside the project, engineers had to solve complex challenges including soil stabilization, heat expansion, wildlife protection, and large-scale logistics while coordinating thousands of workers and heavy machines along the entire corridor.
深入项目内部,工程师们必须解决包括土壤加固、热胀冷缩、野生动物保护以及大规模物流调度在内的种种复杂挑战,同时还要协调整个走廊沿线的数千名工人和重型机械协同作战。

Completed in 2017 after just three years of construction, the railway dramatically reduced travel time between Mombasa and Nairobi while transforming regional transportation and trade.
这条铁路于 2017 年竣工,仅历时三年建设,它极大地缩短了蒙巴萨与内罗毕之间的通行时间,并彻底改变了该地区的运输与贸易格局。

Mandarin Tech takes you behind the scenes of this enormous infrastructure project — where concrete, steel, machines, and human ambition helped build one of Africa’s most modern railways in record time.
《华语科技》(Mandarin Tech)带您走进这一巨型基建项目的幕后——看混凝土、钢铁、机械与人类的雄心壮志,如何以创纪录的速度筑就这座非洲最现代化的铁路。
