Types of freight wagons

Freight wagons are designed to move and transport goods and their task is to transport cargo from the intended destination to the destination, without damage. In terms of appearance, freight wagons are designed in many different types in order to provide suitable quality for transporting various goods. Types of freight wagons are:

Covered wagons

The design of the room of roofed wagons is such that after placing the goods and products in it, by closing the side doors and sealing it, the goods are protected in every way. Therefore, it is very suitable for moving goods that rot in the open air, sun, humidity or other weather conditions.

These types of wagons are made in two forms, two-axle and four-axle. The two-axle wagons have a sliding door on both sides and two vents; If the four-axle roofed wagons have two sliding doors and two vents on both sides. This is to facilitate the loading and unloading of shipments that are loaded and transported in bulk.

In this type of wagons, there are four valves along the longitudinal axis of the roof and six side valves, each of which is completely tightened and sealed by a special toggle in the relevant place, and the roof valves are completely sealed by a rubber band. They are sealed so that no external factors can penetrate.

Flat wagons

Flat wagons are another type of freight wagon that is used to transport hardware and building materials, as well as machinery and heavy goods. Short-edged wagons, like roofed wagons, are made in two types, two-axle and four-axle. The height of the edge of short edge wagons is 400 to 600 mm. The side edges and the hinge head are hinged so that if necessary the side edges are perpendicular to the open rail and the wagon can be used as a flat wagon.

Open top wagon

Open top wagons are mainly used to move and transport minerals and industrial goods and light and bulky goods. These wagons are available in three types: two-axle, four-axle and six-axle, and have one or two double-hinged hinged doors on each side. The rear body of some of these wagons can be opened and closed around the upper hinge. Also, in the floor of some of these wagons, valves have been installed so that the evacuation operation can be done from the floor of the wagon after releasing the side toggle.

Flat wagons

Flat wagons are used to transport heavy and heavy machinery and goods, as well as iron parts such as iron sheets and beams. Flat wagons are designed in normal and wide types, in two axles, four axles and six axles. Flat wagons are equipped with steel columns to restrain the goods, which can be rotated 90 degrees from the upright position and placed horizontally along the side chassis.

A special type of flat wagon, known as a backbreaker, is used to transport high and heavy goods.

In general, flat wagons have edges at both ends that are loaded on the tampon when loading so that vehicles can pass from the loading platform to the wagons or from one wagon to another.

Tank wagon

Another type of freight wagon used in the rail transportation industry is tank wagons, which are used to transport liquids, petroleum products and gases. Like other wagons, tank wagons are available in two types, two-axle and four-axle. The thickness of the cylindrical body of the tanks is between 8 to 12 mm and covered with steel sheet. At the top of the tank wagons is a large circular door with a sturdy lid. These doors are not suitable for human doors and repairmen can enter the source through these doors and make the necessary repairs. There is another door next to this main door, which when opened, the drain valve can be seen. There are also two valves in the wall, one of which empties the gas inside the tank and the other valve empties the tank during evacuation.

Also, in the lower part of the tanks, there is a drain valve branched from the route and these drain valves are equipped with a lid. All drain valves and the main circular lid can be sealed.

Refrigerator wagon

Refrigerated wagons are used to transport perishable goods that spoil in the presence of air and heat. Perishable materials include vegetables, meat and fish, dairy products, etc. Fiberglass, acoustic sheets and lead sheets have been used to insulate refrigerated wagons. Inside the refrigerated wagons, various compartments are installed for loading goods with different temperatures. The temperature of these chambers is between -20 degrees to +4 degrees.

Inside this type of wagon, there is a cooling compressor that is connected to the engine and ammonia cooling gas tank and cools the air inside the wagon during operation. These wagons are inspected by a person in charge at all times of loading and transportation immediately after loading and the engine must be switched on.

The side doors of the wagon have plastic shingles which, after closing, prevent heat from penetrating from the outside into the wagon and vice versa. This type of wagon, like other wagons, is made in two types, two-axle and four-axle.

Ballast wagon

Ballast wagons, which are another type of freight wagon, are used to carry materials such as coal, iron ore and the like. In other words, this type of wagon is a special type of long-edge wagon that due to the type of use and application, changes have been made in its structure. The rake wagons are made in two types of two-axis and four-axis and are equipped with a number of discharge valves along the longitudinal axis at the bottom of the wagon.

Car wagon

Wagons are used to transport passenger cars or light freight vans from the factory to distribution centers. There are two types of carriages: roofed and open. The length of open wagons has reached 25 meters, which is suitable for loading 12 to 15 cars. One of the main problems of this type of wagon is the lack of protection of the car against damage caused by weather conditions.
