Rolling stock repair

Car maintenance is a mandatory set of actions aimed at maintaining the correct operation of the rolling stock. The main criteria for checking high-quality maintenance are the operability, as well as the serviceability of the cars. For the constant active use of the car fleet and its maintenance in an exemplary working condition, the international technology of car repair is used - the ISO 9001-2009 quality standard's system.

The system of maintenance and repair of Type-Trans cars in all respects meets all international quality standards. For our work, we use only modern proven equipment, because a really good repair of rolling stock is, first of all, compliance with current requirements and quality standards. The company also provides services such as axle box repair, urgent car repairs, freight car wheel set repairs and many other types of repairs in the field of railway transport.

Repair of railway cars of different types has a common structure, but some of the nuances of the work are still different. The types of railway cars differ depending on the following factors:


car body structure;


methods of loading and unloading goods;


the nature of the transported cargo;


the presence of a cooling or heating system in the car;


capacity and tonnage of the wagon;


maximum permissible speed of its movement.

Different types of freight cars have different parameters and are used for different types of cargo. What are the types of freight cars?

covered wagon - used for the transportation of goods that need protection from rain, snow, moisture or oversized influence of the sun. The body is a simple platform that consists of a roof, floor and walls. In most covered wagons, loading and unloading takes place through doors in the side walls;

tank - used for the transportation of gases, liquid substances and powdery materials;

gondola car - a type of car that is used for the carriage of bulk and bulk goods, which does not need protection from atmospheric precipitation. The absence of a roof in some of the specimens makes it possible to fully automate the process of loading and unloading through the hatches;

hopper car - designed for the transportation of heavy bulk, as well as bulk cargo: cement, fertilizer, carbon black and various crops of grain plants. This type of wagon is called self-unloading, because the cargo is unloaded by opening the lower opening of the hatch under the influence of gravity;

isothermal wagon - a covered freight wagon for the transportation of perishable goods. Unlike a refrigerated car, this type of car cannot boast of a refrigeration unit - maintaining the desired temperature along the way is carried out due to thermal insulation made of polystyrene and other materials;

refrigerated car - the main purpose of a refrigerated car is the transportation of perishable goods, long-term transportation of which is possible only at low temperatures. This microclimate is created through the use of special cooling equipment;

dump car - used for the transportation of bulk cargo: sand, coal, crushed stone, various types of rocks, ore and many other building materials. They feature a conveniently folding body that tilts when unloading. Depending on the type of unloading, dump cars are of two types: with hydraulic and pneumatic unloading;

car-carrying car - designed for transportation of cars, small buses, motor vehicles and trailers. They can be covered or open.

There are 4 main types of repair of freight cars of railway transport:


depot repair - carried out in the carriage depot and implies a small scope of work of the assembly-disassembly type. This includes flaw detection, repair and renewal of some component parts of the car;


overhaul - carried out for the fragmented or integral replacement of worn out and faulty car parts with proven new ones;


Routine repair of TR-1 wagons - carried out for wagons that are prepared for transportation with uncoupling from the train and fed to specialized railway tracks;


Routine repair of TR-2 wagons - used for wagons with decoupling from transit trains or from formed trains.

All types of car repair involve a complete inspection. Tip-Trans company focuses on the quality and timeliness of the work performed. The types and periods of restoration of freight cars are of great importance to us, because the speed of repairing damage reduces their downtime.
