Freight train: classifications and features
Freight or freight trains are one of the many components of railway transport traveling around Russia and the world. In addition, the "freight trains" themselves are still divided into numerous categories that have their own distinctive features.
All rail transport is divided into four large groups:
- following special requirements;
The most numerous category is the first. It includes fast, high-speed and high-speed trains, human (freight train filled with people), cargo-passenger, passenger, brand-name (comfortable passenger train, for example “Red Arrow”), premium categories, commodity, accelerated freight, post-baggage, household, military, sanitary and locomotives without cars. To extraordinary include fire, recovery and snow cleaning compositions. Upon special request, armored trains (armed and armored combat personnel created to take part in hostilities within the railroad) follow,Lettered (have the highest priority on the main line, since important people carry especially valuable cargoes, the name comes from the fact that such transport is indicated not by numerical value, but by letter - by a letter) and mourning (often used in the past at the funerals of national heroes and prominent rulers ). Currently obsolete are courier trains, which are moving at high speed and are letting in small stations. However, the concept itself is obsolete, as high-speed trains and express trains are now moving in this way.
The cars are also divided into their own categories: passenger, cargo and special. The latter include such as a rail lubricator, laboratory, safe, tender, laundry, rail grinding, weighing, measuring, washing and disinfecting and others.
Features of the freight train
Freight train (freight) is a train comprising a group of freight cars led by a locomotive. He has features. The length of a freight train may be different, it depends on the number of cars, which in composition may be on average 50-70. The longest trains reach 2 km.
These trains are also divided into their own categories: covered, tanks, thermoses, glaciers, platforms, hoppers (for bulk goods), refrigerated, isothermal, car carriers, conveyors. At the same time, their design is almost the same: truck, body, frame, braking device and automatic coupling. The speed of a freight train in Russia is limited to 90 km / h. In the world, this indicator in some countries reaches 120 km / h.
Classification of freight trains

- pass-through - traveling no less than in one commodity stop;
- assembly - delivering cars to intermediate stops;
- export - pick up cars at intermediate stations on its route;
- heavy - exceeding by a hundred or more tons the weight norm set at the following point;
- long-haul - having at least one conditional wagon more than the maximum rate for a certain section of the track;
- increased weight - more than 6 thousand tons;
- increased length - more than 350 axles, including the axis of the "tractor";
- connected - two or more interconnected freight trains, each with its existing locomotive.
Accelerated freight trains also run on railways: fast freight, refrigerator, specializing in the transport of livestock, poultry and perishable goods.
Nominal freight trains
If in Russia freight trains have only numerical designations, in the USA it is customary to give them their own names, and to decorate the cars with advertising. Such a freight train usually delivers vegetables, fruits and herbs to their processing sites. The movement of these trains is strictly limited by the schedule, the route speed is high.
Although at present the freight train already has many varieties with its own unique features, they will be replenished and upgraded in the future.
