We first bought such cars for the 1980 Olympics, and some of them, having gone to serve the subway, still work there. But over thirty years, much has changed, although structurally Unimog is the same cross between a truck and a tractor, featuring a spring suspension with huge strokes and fantastic cross-country ability. The current “locomotive” was built from the popular U400 medium-tonnage, which was equipped with a bunch of air cylinders, a couple of railway axles and couplings. According to the manufacturer, this particular modification is capable of towing up to 1000 tons! And these are 12-13 cars.
A universal car is capable of dropping onto the canvas anywhere and pulling behind 1000 tons or 13 empty wagons

Rolling wheelsets - guides. The moment pass wheels with tires. The coefficient of adhesion in a pair of rubber-steel is six times higher than in a pair of steel-steel. Steel wheels are raised and lowered using a hydraulic actuator, and the pressure determines the computer taking into account the load. Own weight of the railway "Unimoga" only 12 tons.
They did not replace the engine with a diesel engine - there is a 238-horsepower in-line “six” Mercedes-Benz OM 906LA. So that the tractor could start with a load of 200-500 tons, a hydrodynamic transformer was built into the transmission. It enhances the torque by two and a half times, which allows Unimog to move smoothly without engaging the clutch, preventing its wear. The torque converter has a double clutch and an automated Telligent gearbox with eight forward gears and six reverse gears. The maximum speed is limited to 90 km / h, but this is a requirement not of railways, but of ordinary truck roads.
The Unimog, like any shunting locomotive, was hung with signal lights: three white in front and one red in the back. They automatically switch when Unimog changes direction

To touch and disperse the 1000-ton composition is half the battle; it is important to stop it. To do this, use regular car pneumatic brakes. In order to fill all the braking mechanisms with air, four 85 L receivers were mounted on the frame of the locomobile. A pressure of 8 bar is provided by a hydrostatic compressor. Productivity 540 L / min. The total air supply is enough to service 13 cars (52 axles).
In order to climb onto sleepers, Unimog does not need to move, it is able to get on rails anywhere - just five meters of a straight path. Drove in, lowered the guides, picked up the car - and touch! For everything about everything, five to seven minutes.
On a regular road, this “uni” can be identified by a narrowed track (1520 mm) - the same as that of the Russian railways

The operation of a small “uni” is cheaper than a shunting diesel locomotive. In addition, it can be forced to clean the yard and drive it to the store. After all, this is a car! But, remaining the king of universality, Unimog is valued royally. This copy, with additional equipment (snowplow and sweeping brushes), costs about 16 million rubles. They say there are already orders for these. I'm glad: the train started.
