Brake trains

Increased weight and length of freight trains - one of the major events in the development of ever-increasing traffic volumes of national economic cargo. It is advisable to first and foremost on those areas where there are virtually exhausted the capacity, the less busy routes pass trains increased weight can increase mezhpoezdnye intervals of a given volume of traffic, creates more favorable conditions for the maintenance and repair of technical equipment (path, the contact network, communication devices, SCB, and others).

Skipping the increased length of trains increases the carrying capacity, slightly reduced throughput, due to large mezhpoezdnyh intervals, especially given the need to reduce the maximum speed for certain categories of such trains.

Let us take an example, two versions of freight trains, one of length 800 m, the other - 1800 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 sites delimiting the train, n = 4. For the first version of the train we obtain t mp = 360 s, and for the second t mp = 432.

The train weighing more than 6 thousand tons are prohibited include cars, two-axle, with oversized cargo-fourth or more degree, with bit weights of the fourteenth and more level, with people, coaches can only be in the rear of the train, if the end of the train engine is not installed feeding a compressed air brake line. Coupled locomotives when they are available not only in my head, but also in the composition or rear of the train should operate as many units, so as not to distract the driver's head on the engine an extra pass commands.

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

Subtopics:

• 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
• Connection freight trains
