Valuable linear motor(linear motor) subway station. The subway is an urban rail transit system that operates mainly underground. It is an abbreviation for "underground railway" or "subway." It is well known that the birth of the subway has facilitated human life, shortened travel times, and to some extent eased urban congestion. But do you know how much it costs to build a subway? According to the knowledge of the Linear Motor(Linear Motor), the cost of the subway per kilometer increased from 500 million yuan in the early period to 700 million yuan, and the cost of Beijing even exceeded 1 billion yuan per kilometer. In terms of the purchase of subway trains, Shanghai Line 1 costs US$ 1.36 million each, Guangzhou is higher, and Nanjing Metro, which has better cost control, has US$ 1.16 million per train.
What? And that's all the chin and eyes? The information that the linear motor(linear motor) small editor will share next will be expected to impact everyone's cognition with the overwhelming trend and thunderous force! The Boliteni subway station in Bucharest, Romania, looks like nothing special, but its marble floor is a fossil 80 million years ago.
The Boliteni subway station was built in 1983. Construction workers obtained limestone slabs from nearby mountains and used them to build subway stations. At that time, no one knew that the strange and beautiful patterns on these slabs were actually fossils of prehistoric creatures. Most of these fossils belong to a species of marine life that lived in shallow seas from the Late Jurassic to the Late Cretaceous period. When the local shell plates collided, the land carried marine animals living in shallow waters. Rising from the sea, it became a mountain. For tens of millions of years, the exoskeleton and body of these marine animals were petrified in limestone and later used by workers as limestone to build subway stations.
The small editor of the linear motor(linear motor) once paid attention to the "World Collection" hosted by Wang Gang for a period of time. Some of the vessels left in the Ming and Qing dynasties were of great value. The subway built with fossils 80 million years ago was naturally valuable.

When it comes to subways, I wonder if you 've heard of a new type of linear motor(linear motor) subways? In China, Guangzhou Line 4, Line 5, Line 6, and Beijing Airport Line are all driven by linear Motors(linear Motors).
