The fuel tanker is installed on a railway platform using fitting stops and is additionally attached to the floor of the railway platform. The tanks, rigidly fixed in a metal box with an inclined bottom, are double-walled with the formation of an inter-wall space between the two walls, which is filled with nitrogen, and the internal cavity of the tanks is separated by breakwaters, the tanks are covered with circumference with a dense insulating cover, while the top of the cover is a dense tarpaulin, and the inner part is made of stone mineral wool insulation; holes are provided in the lower part of the insulating cover within one third along its entire length.

The fuel tanker is a three-dimensional all-metal structure consisting of a steel power all-welded frame 1 with an upper base and compartments, including a steel base frame and a steel cover frame, which are interconnected by steel posts along the perimeter and corners.

The side walls, the upper base, which are removable sections of the roof 9 and non-removable sections of the roof 13, are made of steel sheet of at least 3-4 mm, and the flooring is made of corrugated sheet of at least 4 mm.

To increase the structural rigidity of the tanker, to prevent roof failures during multi-layer accumulation of snow and ice in winter, and to drain melt and storm water, the removable sections of the roof 9 and the non-removable section of the roof 13 are made pitched.

The fuel tanker includes compartments: at least one compartment is made for a tank 2 with hatches 28 and equipped with ventilation with louvered grilles 26, and located next to it, at least one compartment of a technical room 22, equipped with side doors 14. The block module is equipped with swing end gates 17. The compartment for WGS 2 is separated from the technical room 22 by fire partitions 32, ensuring fire safety of equipment and personnel in the technical room 22.

In technical room 22 there is technological and control equipment with the possibility of interaction between tanker devices. The equipment includes a global positioning system 6; at least one fuel dispenser 7, which is connected by a pipeline to the tank 2; automatic drum - reels 8; automation system 10; fuel terminal with software 18; compressor 19; filling pump 20; pumping unit 21; fire extinguishing control system, alarm and warning system 23; heating and ventilation control system 24; powder fire extinguishing module 25; generator set 29 and control panel 31.

Inside each compartment, in the places where steel boxes with an inclined bottom 3 are installed in the lower part and on the sides of the tanker, there are additionally steel struts (not shown), reinforcing the frame 1 and the ribbing of the steel struts at an angle of at least 3° from the side of the swing end gate 17 towards middle of the block module. The tanks 2 are located and rigidly fixed on steel boxes 3 by welding continuous seams to the floor and side walls of the tanker inside the all-welded frame 1.

At least one fuel transfer pump 4, equipped with a humidity sensor 15, is fixedly installed in each steel box 3, together forming an automatic overflow protection system and ensuring the pumping of spilled fuel back into the tank 2. Fuel transfer pumps 4 are bolted to the steel floor box with an inclined bottom 3 in its lowest part.

A pump 4 installed in each steel box 3 with a humidity sensor 15 serves to return diesel fuel back to the tank 2. When fuel leaks from the tank 2 into the steel box 3, the permanently installed fuel transfer pump 4 in the latter automatically turns on, which ensures pumping of the spilled fuel back to tank 2.

Fuel transfer pumps 4 are turned on and off by signals coming from humidity sensors 15. When fuel is spilled from tank 2, a signal is sent from humidity sensor 15 to the automation system 10, which supplies electrical voltage to the fuel transfer pump 4, automatically turning it on. After pumping the spilled fuel back into tank 2, pump 4 is automatically turned off by system 10.

In this case, the signal to turn on the fuel transfer pump 4 is supplied from the humidity sensor 15 when spilled fuel gets on it. After pump 4 pumps all the spilled fuel from box 3 into tank 2, the humidity sensor 15 is no longer affected by the spilled fuel, the transmission of the signal from the humidity sensor 15 to the system 10 stops, and the pump 4 is turned off.

Steel stops and anchor bolts are rigidly installed in the box 3 for rigid fastening along the entire perimeter of the steel supports of the tanks 2 through the removable section of the roof 9 to the bottom of the box 3.

Reservoirs 2 are used, preferably with a volume of at least 13.5 m ³ , with each tank 2 separated by breakwaters 5, and the interwall space of each tank is filled with nitrogen and contains gas pressure sensors. The presence of nitrogen pressure is controlled by an automation system 10 with information output to the control panel 31.

Making tanks 2 with the formation of an inter-wall space between two walls, which is filled with nitrogen, is carried out to protect against fuel leaks and identify leaks.

To preserve the properties of the metal in conditions of especially low temperatures, tanks 2 are covered around the circumference with a dense insulation cover with a thickness of at least 50 mm, while the top of the cover is a dense tarpaulin, and the inside is made of stone mineral wool insulation, in the lower part of the insulation cover within One third along its entire length there are also holes provided to prevent splashing and accumulation of fuel in the insulating cover when fuel leaks from the tank, so that the fuel flows directly into the steel box 3.

Filling each tank 2 can be done in three ways:

- on drain-loading racks through a top-loading device into the upper hatches of 28 tanks 2;

- using filling pump 20;

- through the sleeve of the fuel tank into the upper hatches 28 using the pumping unit of the tank.

At the ends of the tanker there are swinging end gates 17, providing access to the outer ends of the tanks 2. Removal of tanks 2 for maintenance and repair is carried out through a removable section of the roof 9, on which service platforms with removable fencing are mounted, while on the swinging end gates 17 they are provided and secured ladder for climbing to the roof 27.

The ends of the tanker are equipped with inter-car connections to enable its connection with similar tankers and/or energy cars and its further transportation by rail. The inside of each compartment with tanks on one side is equipped with channels for storing pressure hoses 16.
