Train SVG in the modern concept is a formed and coupled train consisting of a group of wagons, with one or more operating locomotives or motor wagons that drive it, and has installed signals (sound and visible), which indicate its head and tail. In addition, on many (including Russian) railways, each train receives a certain number that allows it to be distinguished from other trains. Trains also include locomotives without cars, motor cars and special self-propelled rolling stock (e.g. caravans and fixed-types) that are sent to the ferry and have installed signals.
Train SVG Definition of concept
Although the word “train” is traditionally associated with railway transport, it appeared much earlier than the first steam locomotives (1804). Thus, according to Dahl’s dictionary, the word “train” comes from the word “trip” and originally meant a number of carriages following each other – in this sense the word is preserved, in particular, in the phrase “wedding train”.
Later on, with the development of railway transport, the word “train” was applied to it as well. In the same Dahl’s dictionary you can find the following definition: “Railway train – how much the locomotive carries, or what is linked together, in one whole. This definition also applies to a group of interlocking cars – a railway train.
As the use of horse-drawn carriage decreased, the word “train” gradually lost its original meaning (“a number of carriages”) and became associated solely with the railway.
Locomotives without carriages, motorcars, caravans and fixed-type locomotives sent to the ferry are considered as trains.
Thus, not every train can be called a train in the official sense; in turn, the availability of cars is not a mandatory condition of the train.
Train SVG History
On September 27, 1825, the first public railroad between Stockton and Darlington was opened. The first Train SVG on it was carried out by the Locomotion steam train, whose name later became commonplace and later not only steam locomotives, but also other self-propelled rail carriages began to be called locomotives. On September 15, 1830 the first railway line Liverpool – Manchester was opened, on which the movement of trains was carried out only by locomotive traction, and also for the first time the movement of trains was ordered by introduction of the schedule of movement. On October 30 (November 11), 1837 the Tsarskoye Selo Railway was opened, which became the first public railway in the Russian Empire.
The organization of train movement begins to be formed, including, in addition to the schedule of movement, an alarm system is introduced, when trains begin to differentiate in space, and the locomotives themselves are equipped with signals to warn of approaching. In the second half of the century, the improvement of the rolling stock itself began, including steam locomotives, which became stronger, which made it possible to increase the weight and speed of trains, and metal frames instead of wooden ones began to be used in cars. In addition, pneumatic brakes are being created and introduced, which additionally increases traffic safety, as well as the first locomotive speed gauges with the ability to record traffic parameters. The USA and Russia are building the world’s largest railroads, the American transcontinental railway and the Trans-Siberian railway, respectively. By the end of the century, the United States had begun to introduce a coupling system that would allow for higher traction forces and therefore not limit further train weight growth. In the Russian railways, the truck coupler has been used extensively since the 1930s.
In the first quarter of the 20th century, the design of the rolling stock continued to improve, including locomotives with five and more moving axles starting to operate in the loaded directions, and in the 1920s, the industry mastered the production of four-axle cars with higher load capacity. But in addition to steam traction, the railways are gradually gaining popularity and electric, especially in urban transport, and in 1924 Russian engineers are testing the world’s first mainline diesel locomotives. By the middle of the XX century the design of new locomotives continued to develop, while the design of steam locomotives reached its culmination in the form of real giants – Union Pacific Big Boy, weighing more than five hundred tons, produced in the early 1940s. But by that time it was already obvious that the design of the locomotives had become obsolete, so since the 1950s, a number of countries have been discontinuing their production, thus starting a mass transition to locomotive and electric traction, which gives a significant increase in the weight and speed of trains.
