Rail Transport

The use of aluminum in rail transportation began almost immediately after the advent of mass production of aluminum.In 1894, the New York, New Haven and The Hartford Railroad (then owned by banker John Pierpont Morgan) begins production of aluminum seats. of special ultralight buses. However, initially there is a greater demand for aluminum in the freight sector and ideally you want to keep the weight of the vehicle to a minimum to maximize the A limited increase in the amount of cargo that can be carried.a

Today, aluminum trucks are used to transport coal, various rocks and minerals, and grains, while aluminum tankers are used to transport acids. There are also specialized vehicles used to transport finished products such as new cars from manufacturing facilities to dealers. An aluminum truck is one-third lighter than a steel truck. Its higher initial cost can be recouped in the first two years of operation because it can carry more cargo. At the same time, aluminum does not corrode as easily as steel, so aluminum vans have a longer life span, with an average loss of only $20,000 over 40 years of operation. 10% of the value. In passenger cars, aluminium allows manufacturers to reduce weight by up to a third compared to steel cars. In rapid transit and suburban railway systems, significant energy savings can be achieved because aluminium cars require less energy to accelerate and brake. In addition, aluminum cars are easier to produce and have far fewer parts. In long-distance rail systems, aluminium is widely used in high-speed rail systems, where it was introduced in large numbers in the 1980s. High-speed trains run at speeds of 360 kilometers per hour or more. The new high-speed rail technology is expected to achieve speeds in excess of 600 kilometres per hour.

Aluminum reduces the weight of such trains, thus reducing the bending of the tracks that increases frictional resistance. In addition, high-speed trains, like airplanes, must have an aerodynamic shape and a minimum of protrusions, and the element aluminum It also helped designers in this regard. France's TGV high-speed rail system used high-speed trains made of aluminum.In the 1970s, Alstom (France) began to Trains were developed for this network and the first line connecting Paris and Lyon was opened in 1981. Today, the TGV is the largest high-speed rail system in Europe and is planned to serve as the basis for a Europe-wide high-speed rail system. The first TGV trains were made of steel, but in later generations, aluminium replaced steel. As a result, the latest model of the train, known as the AGV, is made entirely of aluminium and can reach speeds of up to 360 kilometres per hour. Today, AGV trains are built only by Italy's Nuovo Transporto Viaggiatori Rail system operations. The body of Russia's first high-speed train, Sapsan, is also made of aluminum alloy. Maglev technology is the next step in the development of high-speed railways. Magnetic levitation trains are suspended in a dense magnetic field so there is no frictional resistance on the track. This means that maglev trains can reach unprecedented speeds. In a test in Japan, speeds reached 603 kilometers per hour.
