High-speed train is a railway vehicle that provides the opportunity to travel faster than normal trains. Trains that can travel at a speed of 200 km / h on rails laid with the old system and 250 km / h on rails laid with the new system. Located in Ankara-Eskişehir high-speed train line in Turkey and traversing a distance of 245 km in 1 hour and 25 minutes, is Turkey's first high-speed train.

Turkey's 2nd fastest train, 306 km from the Ankara-Konya line is 1,5 times per hour. TGV in France, ICE in Germany and Magnetic rail trains in development are examples of this type of train. Currently in Germany, Belgium, China, Finland, France, South Korea, the Netherlands, England, Spain, Sweden, Italy, Japan, Norway, Portugal, Russia, Taiwan, Turkey with the trend over time of at least 200 mph realizes this transport.

Develop a fast train to have a fast train line the iceberg's appearing face. Because the most important factor that ensures the success of the system depends on the lines to be created. High-speed trains require high-speed rail lines to support this speed.

The UIC (International Railways Association) and the European Union define the definition of “High Speed ​​U on the same basis. The UIC High Speed ​​Department and the European Union's 96 / 48 and 2004 / 50 / AB directives have defined a number of systems under the high speed heading. The lines below the standard determined by these definitions are accepted as ansiyon Conventional (Traditional-Classical) Bu.

What is High Speed ​​Train?

There is no single standard definition for high-speed rail concept. The definition of high speed varies according to some criteria due to its complex structure. In order to avoid noise problems in areas where population density is high, it is seen that speed is limited to 110 or 160 km / h in terms of capacity and safety related reasons in high speed lines with 180 km / h and special tunnel and long bridges.

1. In terms of infrastructure

In terms of infrastructure, the definition of high-speed rail covers many concepts. If the infrastructure of the line is newly built to allow trains to be operated at speeds of 250 km / h and above for the whole or at least a large part of the journey, it is defined as a "High Speed ​​Line". Again, in conventional lines suitable for transportation up to 200 km / hour, although there are speed limitations due to passages from mountains or straits, use of narrow rail spacing or other special reasons, these lines are accepted as "High Speed ​​Line".

2. In terms of Pulling and Pulling Vehicles

"High Speed ​​Train" is a series of fixed-gear engine and wagon sets that can reach a speed of at least 250 km / h and above, used in commercial services. Under certain conditions, train types that operate at lower speeds (200 km / h) but offer high-quality services such as tilting body trains can also be defined as high-speed trains.

3. Operating Systems

For this definition, which varies according to railway management, 4 has a separate case.

• The most classical system in high speed train management, high speed trains operate on their own lines, conventional trains operate on their own lines. Such are the JR East, JR Central and JR West Shinkansen lines in Japan.

• Only high-speed trains operate on high-speed train lines. On conventional lines, both conventional trains and high-speed trains operate at conventional train speeds. Such are the lines operated by SNCF in France.

• Only conventional trains operate on conventional lines. On the high-speed train lines, on the other hand, high-speed trains and conventional trains can work together. However, as conventional trains will travel at lower speeds, the capacity is decreasing. Such are the lines operated by RENFE in Spain.

• Conventional and high-speed trains can run together on the same lines. This is the case in Germany and Italy. Germany (DB AG) and Italy (Trenitalia) Railways plan all train traffic by taking high-speed train traffic into account.
