The first empty rail line opens with all-aluminum carriages showing majesty

News from this newspaper: Recently, the first phase of Wuhan Optics Valley Sky Rail Project was put into operation. This is China's first suspended monorail commercial operation line, a milestone in the development history of China's rail passenger lines. The Optics Valley Skytrain is located in the Wuhan Optics Valley Ecological Corridor and can be interchanged with Metro Line 11. It greatly facilitates the travel of residents and workers along the line and is of great significance in promoting regional economic and social connections.

Empty rail is the common name for suspended monorail trains among the people. It is a new type of urban rail transportation with low and medium transportation capacity, eco-friendly, green and low-carbon. The Empty Rail train carriages are suspended below the track beams and run in the air, forward or backward. , folk call it "flying", but in fact it is not flying at all. The advantages of this "sky train" are that it does not occupy any land, has strong environmental adaptability, a large view of the landscape, and good effects. It can be used for commuting, as well as for sightseeing and sightseeing.

The first phase of the Guanggu Sky Rail Line is 10.8 km long and has 6 stations. It operates fully automatically and without driving, with a maximum operating speed of 60 km/h. The grouping is flexible and can have 2 or 3 carriages. Each carriage can have 2 carriages or 3 carriages. Each carriage can accommodate more than 110 people. The train starts, stops and runs smoothly and comfortably, with no vibration, impact or friction, and no interference to the environment. It can pass through residential buildings and run late at night, adding a lot of fun to travel and sightseeing. Sky rail trains use rubber pneumatic tires and adopt air springs and other shock-absorbing technologies similar to those of high-speed rail, which greatly improves the stability and comfort of sky rail vehicles. In addition, there are also innovations in the construction of sky rail stations. The bridge construction is separated. The bridge is completely separated from the station building and the station does not bear the dynamic load of the train.

The suspended carriages used in the Optics Valley Sky Rail are required to be as light as possible, so they are made of lightweight metal materials. Among the four lightweight metal materials used today - aluminum, magnesium, titanium, and aluminum-based composite materials, aluminum alloy has the highest cost performance. In order to achieve the lightest goal, the "Optics Valley Photon" carriage is made of all aluminum. The so-called all-aluminum construction means that under the existing technical conditions and on the premise of ensuring safety and ride comfort, all parts that can be made of aluminum alloy are made of aluminum. The carriage uses aluminum alloys such as 3003, 5083, 6063, 6N61, 7075, and A390. The aluminum body rate is over 89%, which is the highest level currently.
