Matisa, Theurer or Plassermatic. We took a look at the “invisible workers” behind the scenes of the underground

Matisa PV-6 and Plasser & Theurer EM 50 mic cars
around the wagons there is a check of the geometrical position of the rail clamp – i.e. a simplified one, whether the rails have the correct gauge, whether the rails should not run over the heads, the carriages according to whether they are fixed, whether they are collapsing or not, the distance and age of the original rails, and so on. The first train of this type was purchased for the Metro from the Matisa company in 1973. The record is made for continuous runs when the original rail is turned off using three small trains and two traveling trains. The transfer from the small devices is carried out mechanically with the help of towing chains and pulleys with levers on the signal device. The recording device consists of eight bolts and a gearbox, on which a millimeter scale is moved, the purpose of which is to record the driving speed, explains Ivo Janeck, an operational employee of technology and construction. Five years ago, the car was thoroughly modernized, the main change being the built-in technology into the car. The movement of the fingers on the paper in the mic counter was transferred with the help of an electric impulse to the PC and the result is a graph in the form of a picture. The new parameters have two inputs, a paper graph from the micho console and a graph from the PC.

In 2003, a new Austrian mic vz EM 50 began to be used for the same purpose (name of the photo on the right including the view into the cabin), which 15 years later was able to modernize and use new technology with the help of laser, camera and induction sensors. Wheel load, including tunnel profile control, can be controlled at a maximum operating speed of 40 km/h with the original rail on. Take care of the staff.

Plassermatic 08-75 GS automatic machine undercarriage
This twenty-seven-tonne special rail vehicle was purchased for the metro in 1989 from the Austrian company Plasser and Theurer from Linz. It is used for cutting and repairing sub-tracks, where rails, kens and switches are fixed to the washers in the trk loi. It’s around, as it is, according to a very simplified description of the direction and age to correctly adjust the position of the track. After modernization from the early 2000s, the machine was equipped with controls for external operation.

Pvsn cars
DPP has plates available in various versions and they are intended for general transport of cargo, but a variety of specific structures are mounted on them. It is, for example, a ladder with two steps, an inspection cabin, a template for changing the passage profile, which has handles for transporting cable studs, has foldable and removable old trunks, and the like.

The PV 52 truck transports equipment for welding the rails with termite to the site. What’s going on? The termite powder is poured into a special container and turned on. After burning, the molten iron flows into the form surrounding the ends of the rails, filling the gap between them and forming a high-quality rail.

Motorized Universal Vehicle (MUV)
The legendary muvka was and is portrayed in various versions as a small but honest worker not only in the world of the subway, but also as a sink on other railways. It is a two-axle platform vehicle with drive on both axles and equipped with a relatively large closed cabin at the front. Carts are used to transport material, people, and so on (often a barrel is also used) and can carry heavy work equipment. First of all, the universality of the trolley, when it can be modified to perform various types of repair and maintenance work on the track with the help of additional devices. The creator was the shape of the SD Mechanization of the grass economy Praha watershed Brno-Horn Herpice. Since 1974, the MUV car modification served as a special urn for the needs of the Prague underground in the rural metropolis. Late reconstructed and modernized versions are for example marked MUV 69.1 and MUV 69.7, MUV 71, MUV 73, etc. The manufacturer supplied the truck with a mounted hydraulic arm, this device was added to some trucks.

Now, eight MUV 73 type trolleys, two MUV 74M trolleys and similar universal WB 10.1-M trolleys, of which DPP employees have ten at their disposal, make up eight MUV 73 trolleys.

Locomotive series 797.8
The distance between the so-called auxiliary traction means. Prague metro workers have 17 of these diesel-electric two-way rail locomotives at their disposal, although they are designated as T1 and T18, because one of them was sold to Hungary. In operation, they are designed for easy movement with railway cars on trains, cars for the transport of passengers and special cars at depots and for the transport of service trains in tunnels.

They are equipped with a Liaz engine, in the case of a T18 Caterpillar, the maximum operating speed is 40 km/h, and when the gimbals are removed, the transport speed is 50 km/h. One of the original locomotives, the 703.6 locomotive, has been preserved.

SVM 12 subway special trolley drill
It is a towed vehicle on the carriage of the MUV 69 frame, on which a local drill is mounted to the drilling hole for the installation of the anchor bolts of the carriages and the original rail. On the cart, there is a container with a water tank for cooling the agitator and jumps for above. DPP has two of these special cars available.

From studs to designer spades The first to travel underground were Soviet cars of the E type, delivered to Slovakia under the EC designation. They were made especially for Prague, developed by Mytiinsk strojrensk zvod. The first six appeared in the capital at the end of 1973, when trial runs were started with them on Kaerov. It was a modification of the E car, which at that time ran in the Moscow and Leningrad metros. The cars had 42 seats and 220 seats, in the 1970s there were 85 of them per day in Prague. The last car went on the track on June 29, 1997. After the end of operation, 79 cars were scrapped, two were sold for scrap and those were preserved as historical vehicles. Historic ride – Es set in Letany station In 1978, in connection with the commissioning of the first six lines of route A, the first Soviet cars of the 81-71 type were delivered, which both came from the Mytiina engineering plant. They were called briquette or ern mushroom, they were put into operation in lt tho year. Gradually, 202 passenger and 302 passenger cars of this type arrived in Prague, but they were never combined in a train with EC cars. V90. years, it was a consortium of companies koda, as, Plze and KD Praha Holdings, as, the aging model was modernized under the designation 81-71M. Independently of the modernization of the Soviet 81-71 sets, the production of completely new cars marked M1 also started. These new cars are light, reach cruising speed and are made of non-toxic materials. The cars have a completely new design that is unique to the world, characterized by the M1 cars of the book Kolejov vehicles, a breakthrough in urban public transport. Out of a total of 730 vehicles, 465 are modernized type 81-71M and 265 are type M1. DPP also has eight historic cars, three ES and eight cars 81-71.
