Braking systems of trains

Increased weight and length of freight trains - one of the major events in the development of ever-increasing traffic volumes economic goods. It is advisable especially in those areas where little bandwidth is exhausted, and on less congested routes pass trains increased weight increases the mezhpoezdnye intervals for a given volume of traffic, creates more favorable conditions for the maintenance and repair of facilities (paths, contact network, communication devices, signaling, etc.).

Skipping the increased length of trains carrying capacity increases, reducing the number of throughput, due to large mezhpoezdnyh intervals, especially when you consider the need to reduce the maximum speed for certain types of trains.

Let us take for example two options for freight trains, one 800 m long, the other - 1,800 m, the speed of the first train 80 and the second - 75 km / h, the average length of one block area of 1800 m, the estimated number of block areas, delimiting the train, n = 4. For the first version of the trains get t = 360 MP, and MP for the second t = 432 s.

The composition of trains weighing more than 6 tons are prohibited include cars biaxial, with oversized cargoes fourth degree or more, with loads fourteenth bit more level, with people, coaches can only be in the rear of the train, if the tail of the train engine is not installed feeding the compressed air brake line. Coupled locomotives when they are available not only in my head, but also in the rear of the train or to work on a system of many units, so as not to distract the driver of the locomotive at the head an additional transfer of command.

The following methods of formation of freight trains increased weight and length.

Subsections:

• Train with the production of locomotives in the head
• Train with the production of locomotives in the head and tail
• Train with the production of locomotives in the head and part of
• The connection of freight trains
