In today's difficult transport conditions, the metro is often the only mode of transport that allows you to move around the city relatively quickly. At the same time, the actual speed of the train in the metro can be different.
The average speed of an electric train in the metro is an average value that takes into account both the acceleration on flat continuous sections of the road between stations and the deceleration of the train when approaching and leaving the station. As a result, the average speed reached by trains in the Russian metro systems is from 40 to 50 kilometers per hour.
In this case, the specific value depends on the length of the routes, the number of stations, the nature of the routes and a number of other factors. As a result, the average speeds in specific cities in most cases fit within the specified framework, however, they may differ slightly from each other.
Thus, the average speed of an electric train in the Moscow metro is 41.3 kilometers per hour, in the St. Petersburg metro - about 40 kilometers per hour. Approximately within the same limits are the speed of train movement in the subways of other cities of Russia - Nizhny Novgorod, Novosibirsk, Yekaterinburg. An exception to this pattern is the Samara metro, which can be called one of the slowest in Russia: the average train speed here does not reach 40 kilometers per hour.
Metro trains can reach their maximum speed on those sections of the track that allow them to accelerate the latter without any danger to the driver, passengers and the train. As a rule, these are rather long sections of the track, with a straight, no turns direction and a satisfactory condition of the rails. If all these conditions are met, the trains used in the Russian metro can reach a maximum speed of 90 kilometers per hour. In practice, however, the maximum speed achieved during movement usually does not exceed 80 kilometers per hour.
Theoretically, the technical characteristics of the metro systems, designed according to the Russian model, make it possible to develop even higher speeds. At the same time, according to experts, the main speed limiter in this case is the design features of subway cars, which are able to withstand the load that occurs at a speed not exceeding 110 kilometers per hour. At the same time, the rails are capable of withstanding the load at a speed of up to 120 kilometers per hour, and the locomotives of subway trains - the load at a speed of up to 160 kilometers per hour.
