- the van would be made with ventilation and heating devices.

- in the van there would be space for a repair team and tools for maintenance of railway tracks and a contact network.

The proposed layout of the vehicle allows you to significantly expand the technical capabilities of the composition, to facilitate the repair, construction and maintenance work and reduce the time of their implementation, due to the fact that:

- the train can move both on railway rails and on highways, while there is the possibility of simultaneous operation of several repair and commissioning teams at different facilities, for example, simultaneously serving the contact network of power lines,

and railway tracks;

- facilitated work with heavy loads through the use of a crane.

The utility model is described in detail in the description and graphic materials on which:

figure 1 is a view from the right side of the composition with the drive wheels lowered and the assembled crane,

- figure 2 is a view from the left side,

- figure 3 is a top view,

- figure 4 is a rear view,

- figure 5 is a plan diagram of a van.

According to the utility model, the self-propelled train 1 is made as a universal vehicle equipped with various repair and installation-construction and operational equipment, capable of moving not only on general roads and on rough terrain, but also on railway rails.

Self-propelled composition 1 is made on the basis of a multi-axle off-road truck and contains the main bearing frame 2.

On the supporting frame 2, a cabin 3 with a power plant, a crane 4 and a van 5 are sequentially installed. In the cabin 3, in addition to the driver’s seat, there can be provided places for passengers.

Self-propelled composition 1 for driving on roads contains pneumatic drive wheels 6.

For driving on highways (general purpose roads), the self-propelled train 1 may also have non-driven pneumatic wheels or, conversely, all pneumatic driven wheels for driving over rough terrain.

The drive of the pneumatic wheels 6 is carried out from the power plant by any known method acceptable in this design, which is not the subject of patenting.

The means for moving on railway rails contains drive

railway wheels 8 and is made in the form of one rear biaxial trolley 9 and one front axle with installed railway wheels 10,

The mentioned railway wheels 8 and 10 are located on both sides of the van at the maximum distance, while the biaxial trolley 9 is mounted cantilever on the rear of the carrier frame 2 behind the rear pneumatic wheels 6.

All drive wheels 6, a crane 4, mechanisms for moving 11 means for moving on railway rails to the working and transport positions, are associated with the power plant of the vehicle, while the mentioned mechanisms are made in the form of hydraulic cylinders.

When operating rolling stock 1 on general roads, the railway wheels 8 and 10 are raised, are inoperative and do not touch the road surface. If it is necessary to move along rail tracks, a biaxial trolley 9 with railway wheels 8 and an axle with wheels 10 are put into working position, for which the mechanisms for moving 11 means for moving on railway rails hang the train together with pneumatic wheels 6 on the rails and install railway wheels 8 on them and 10 (Fig. 4).

For a stable position of the vehicle 1 during adjustment and installation and construction works, outriggers (not shown) fixed on the supporting frame 2 can be provided, the drive of which, for example, is hydraulic, is carried out from the power plant of the vehicle 1.

In the front of the supporting frame 2 behind the cab there is a crane 4, the drive of which is carried out from a power plant of a self-propelled train 1.

Taking into account the purpose of the self-propelled composition 1 and the conditions of its operation, the roof 12 of the van 5 is made reinforced with stiffeners and jibs with the possibility of placement and transportation on the roof 12

In order to expand the operating conditions of the self-propelled composition, the van 5 is made with a ventilation and heating devices (not shown in the drawings) of a known design, and places 15 and 16 are provided in the nutria of the van to accommodate repair crews and tools for maintenance of railway tracks and the contact network, respectively In this case, to improve convenience, the van has two doors 17 and 18 - one is located on the side and the other door 18 is on the rear wall of the van 5. The rolling stock is equipped with a lighting unit in front and behind araturoy known construction and widely used for railway transport.

The inventive tool works as follows.

The main purpose of rolling stock 1 is the maintenance of railway systems, taking into account the heavy traffic load by rail, as well as the branching of the railway network, rolling stock 1 mobile on its own on pneumatic wheels is at the place of operational and / or repair work.

In the absence of a railway section, a temporary collapsible flooring is installed in the area of access to the railway track, ensuring the integrity of the track’s upper structure. The self-propelled train 1 backs up onto the railway track, lowers the drive trolley 9 (wheelset), centers it relative to the track, then the driver-driver unscrews the steering wheel to the maximum angle of rotation of the wheels, turns on the drive of the drive trolley and pulls itself onto the track, includes operation of the brake system and checks the performance of components and mechanisms, including the security system. After that, the flooring is assembled and put into the composition.

Self-propelled composition 1 is ready for operation and maintenance of the railway.

Congress of self-propelled train 1 is carried out when performing entry operations in the reverse order.

As an example of installation work, broaching and replacing a section of a power line can be given. Using the proposed self-propelled train

this process is accelerated by more than two times, since two supports can be serviced at the same time, while the bay with the electric wire will be in close proximity, supported by a crane.

Such an example is not singularly possible, since the proposed tool can be used for other, more diverse purposes, for example, repair of railway tracks, rail replacement, etc.

Thus, the proposed self-propelled train is a universal vehicle, convertible for movement on roads and railways, which can be used as a repair tool, as well as shunting at stations, for transporting goods and people in the conditions of construction and operation of railways.
