Average speed


Average speed of trains in the subway represents the average value taking into account of acceleration in smooth continuous road segments between stations, and slow the train when approaching the station and departure from it. The result is the average speed, which reach the trains in the subways of Russia, is 40 to 50 kilometers per hour.

The specific value is dependent on the length of hauls, the number of stations, nature trails and a number of other factors. Consequently, average speeds in specific cities in most cases fit into this framework, however, may differ.

So, the average speed of trains in the metro of Moscow is 41.3 km / h, in the metro of St. Petersburg is about 40 kilometers per hour. Approximately in the same range are the speed of the trains in the subways of other cities of Russia - Nizhny Novgorod, Novosibirsk, Yekaterinburg. The exception to this trend is the Metropolitan of Samara, which is one of the slowest in Russia: the average train speed does not reach 40 kilometers per hour.

Maximum speed


The maximum speed of the trains can reach those sections of the road that allow, without any risk to driver, passengers and composition to disperse the latter. As a rule, it is quite a long ways, having this direct without rotation direction and the satisfactory condition of the rails. If you implement all of these terms of trains used in the Russian underground, can reach a top speed of 90 kilometers per hour. In practice, the maximum speed achieved in the process of moving, usually no more than 80 kilometers per hour.

Theoretically, the technical characteristics of the metro, designed on the Russian model, help to develop higher speeds. At the same time, according to experts, the main speed limiter at this time are the design features of cars of metro trains that are able to withstand loads encountered at speeds not exceeding 110 kilometers per hour. While rails capable of withstanding a load at a speed of up to 120 kilometers per hour, and locomotives of metro trains - the load at a speed of up to 160 kilometers per hour.
