The image shows from side a hopper wagon assigned for the freight trains, intended for the transport of cereals, such as: rye, corn, barley, oats, wheat, raw rice, sunflower seeds, soybeans.
The wagon is represented in the shape of an embossed rectangle, with the left and right edges cut in a semicircle.
At its base are four pairs of wheels, from the side illustrated as four thickened circles, with a dot in the middle, located two to the left and two to the right of the base.
The car body or outer shell of the wagon consists of an elongated tin container or box covered by a roof with openings alongside the wagon, through which the grain is loaded.
At the bottom, in the center of the wagon, are the grain unloading openings, which have three taps rendered as three small circles cut by a cross.
At the right and left edge of the wagon, on the lower bar, are placed two buffers, highlighted by a short line, thickened and horizontal, with the end joined by a thickened semicircle.
The buffer consists of a piece in the shape of a metal disc, with the role of keeping a certain distance between the coupled wagons and to cushion the shocks between them while moving.
A man is standing in the right bottom corner, thus positioned to facilitate the comparison of the dimensions of the wagon to the height of an adult.
There is one type of wagon for each type of cargo. The reason for such a wide range of wagons is that they are relatively easy to make, especially for manufacturers of metal structures. A wagon is composed of a kind of platform and a container that holds the goods.
Freight wagons for cereals – uagps
These types of wagons used to be used quite often in us. It is less obvious that this type of wagon would be used for grain transportation because of its shape.
They are part of the U series, but they only carry grain.
They have a loading capacity of approximately 56 tonnes and an average speed between 60 and 120 km / h, but usually 100 km / h.
They have a useful volume of 75-80 cubic meters.
The uagps wagons have a welded construction, completely metallic, with gravity unloading.
The grains transported are rye, corn, barley, oats, wheat, rice, sunflower seeds and soybeans.
The wagon has a loading mouth almost the entire length of the roof, which allows loading with conveyor belts or directly from the agricultural silo. And here I refer to those huge concrete agricultural siloes that I used to have near the railway infrastructure. The loading mouth is covered with 4 folding caps.
For unloading, the wagon is provided between bogies with 3 discharge holes, centrally located, in the longitudinal axis of the internal volume. The opening of the mouth is made mechanically by turning a hand wheel. In the older versions of these types of wagons there were hand wheels operable on the platform. But I think it’s changed for obvious reasons. Most U-cars will have a ladder on which you can climb to check the contents of the cars. The first versions of this type of wagon were boxes, like a trailer.
Freight wagons for cereals or cement – ucs
These wagons are also part of the U series, except that they have a slightly smaller capacity. So a smaller weight and therefore less bones.
They can be used for cereals, but also for cement or lime. This cement is dry.
The wagon ucs is also used for the transport of lime or any kind of powdered material which must remain dry. They begin to strengthen if they come into contact with water.
With the wagon ucs can be carried on the site and a ready mix made for concrete, but without water or additives in the form of liquid. The liquids were to be added later. I would say that these wagons usually have a smaller capacity and are usually provided with only two axles.
The wagon ucs can have 3 compartments and 2 axles.
For three-compartment models, silos are smaller than for two-compartment models.
The wagon is loaded and unloaded by spraying the dehydrated material to the maximum capacity. At the top there are some caps that have a seal and screw lock.
