The class M 152.0 railcars (from 1988: class 810 ) of the Czechoslovak State Railways (ČSD) are two-axle diesel railcars for regional traffic. The vehicles form the third generation of two-axle railcars from ČSD.
The vehicles of the ČD series 809 and 810, which have undergone a second modernization since 2018, are marketed as "RegioMouse".
history
In 1973 Vagonka Tatra in Studénka presented the first prototype of the series as the M 151.0001 to the public in October 1973 at the World Exhibition of Railway Technology in Basel . Starting in 1975, seven series of 680 vehicles were built for the ČSD as the M 152.0 series . Appropriate type Blm sidecars were delivered to go with the railcars, which are identical in structure and appearance to the railcars. Two trailer cars could be added to each railcar. Because of the angular superstructure, the railcars were nicknamed "bread box" by railway enthusiasts.
For cross-border personnel traffic to Chop (Чоп) in the Ukraine , two railcars from the 1982 series were given wheel sets with a gauge of 1520 mm (Soviet broad gauge ). These were numbered M 152.5001 and 5002 .
Between 1987 and 1990 the ČSD introduced EDP-compatible locomotive numbers. In the transition period, the EDP numbers were attached with adhesive numbers in addition to the old cast plates. The railcars were given the series designation 810, the sidecar 010. Both successor companies of the ČSD kept the numbering plan, but freely usable sidecars were also added to the passenger car fleet in 2009 by number.
Identical vehicles were delivered to the Hungarian State Railways (MÁV). This referred to the railcars as Bzmot .
After the division of Czechoslovakia into the successor states of the Czech Republic and Slovakia on January 1, 1993, railcars and trailer cars were divided between the newly founded state railways ČD and ŽSR . In Slovakia, the vehicles are now part of the inventory of the successor company Železničná spoločnosť Slovensko (ZSSK).
The vehicles M 152.0002 from ČD and M 152.0517 and M 152.0535 from KŽC Doprava are currently (2016) preserved in their original condition in a museum .
The sidecar 50 54 24-29 174-6 is set up in the parking lot of the Oberschlesisches Landesmuseum in Ratingen - Hösel .
technical features
In contrast to similar vehicles from other railway administrations, the railcars did not have multiple controls , and there are no suitable control cars . Therefore, in multi-part units, each railcar must be manned by a driver. The railcars must always be transferred to the respective Zugspitze at the terminus.
Structure of the railcar
The railcar is a lightweight construction. The car body consists of rolled and folded steel profiles which are clad with sheet steel. The inside of the frame is clad with chipboard covered with Sprelacart . The floor is made of water-resistant plywood 15 millimeters thick and is covered with a two millimeter thick layer of PVC . At each end of the car body there is an entry area which is separated from the driver's cab and which has a pneumatic sliding door that can be closed by the driver's cab as an entrance on both sides.
The passenger compartment has 56 seats in the 3 + 2 arrangement with a central aisle, which were originally upholstered with foam rubber. In addition, one car offers around 40 standing places. The passenger compartment has six windows on each side with a clear width of 1316 by 841 millimeters, the upper part of which can be folded down. The front sides have no car transitions . The driver's desk with the instruments for controlling and monitoring the machine system, the driver's brake valve , a speedometer and a safety driving circuit are located in each end driver's cab . Large windshields with heated windshields, windshield wipers and sun visors enable good route monitoring. By arranging an additional partition, the driver's cabs were very short. To enable the driver to sit in a satisfactory position at all, the partition wall in the area of his seat had to be cut out. The cutout is closed with a sheet metal cover reaching into the entrance area.
The design of the sidecars is the same as that of the railcars, apart from the lack of a propulsion system. Instead of the driver's cab, a continuous bench is arranged at the ends of the car.
Drive and propulsion system
The vehicle is guided by two single-axle bogies, the rear of which is driven by a cardan shaft. This means that both wheel sets can be radially adjusted in an arc. The single-axle bogies are supported by coil springs on the axle bearings. The suspensions are connected to the car body with rubber blocks. The reversing gear for reversing the direction of travel is arranged on the drive axle, which can be sanded on both sides. Both sets of wheels on the railcars are equipped with a wheel flange lubrication device.
A non-charged diesel engine of the type LIAZ ML 634 is installed under the floor as the drive system. This has six cylinders in line with direct injection and is directly connected to the Praga 2M 70 transmission . Apart from the axle reversing gear, the entire drive system consists of components that were taken over from the Karosa ŠM 11 bus . As early as 1971, this drive system was extensively tested on two M 131.1 railcars and had proven itself excellently with a mileage of 100,000 kilometers each. The power is transmitted from the drive unit to the axle reversing gear via a cardan shaft.
The drive system and auxiliary equipment such as water cooling, oil heat exchangers, batteries, fuel tanks and hot water heating are arranged under the floor. Due to this arrangement between the wheel sets, the railcars are not allowed to drive over the overflow mountains. The auxiliary machines, an alternator and a compressor for the compressed air for the pneumatic brake are driven by the diesel engine via a cardan shaft and V-belt. The diesel engine is water-cooled and there is also a fan with a hydrostatic drive . This is regulated automatically depending on the engine speed and the cooling water temperature.
Other facilities
The railcar is equipped with indirect brakes and direct brakes according to the DAKO system. This is controlled with the driver's brake valve Škoda N - 0. There is also a handbrake that can be operated in both driver's cabs. There are emergency brake taps in both entry areas and the passenger compartment.
The passenger compartment of the railcar is heated by warm air. For this purpose, the cooling water from the engine circuit is fed to a heat exchanger that is housed under the seats. When the diesel engine is not running, a preheater is used to heat the air. The driver's cab is heated with a hot water heater. The sidecars are electrically heated. The passenger compartment is ventilated via roof ventilators. The alternator is responsible for lighting the passenger compartment . By equipping the railcars and sidecars with side buffers and a screw coupling, it is possible to couple the vehicles with other railroad vehicles. The railcars can therefore carry out occasional freight transports on branch lines. The screw couplings correspond to the light design customary for diesel railcars of ČSD, the wagons equipped with them may only be set at the end of regular trains.
Conversions
In 1976, the M 152.0001 railcar was converted to the FST-2 measuring railcar . On the basis of the M 152 series , the MVTV catenary inspection multiple units, M 153.0 series , were built from 1981 .
Conversions in the Czech Republic
In 1994 the conversion of 28 units began for conductors-free operation. The interior design was also changed in this context. In 1996 these units were renamed the ČD series 809 .
In 1994 the order was also placed to improve the 810s in terms of reliability, economy and travel comfort. Two prototypes of the 811 series were created . In 2001 a vehicle was converted to the 812 series and used together with a 912 series control car. This prototype was named "Esmeralda" and was the forerunner of the 814 series, with which it has external similarities.
From 2005 to 2012, ČD vehicles were fundamentally modernized and converted by the Pars Nova company . This results in two-part units, each consisting of a railcar and a partially low-floor control car. Some of the multiple units are configured as a three-part unit, consisting of two multiple units and a sidecar positioned in between.
The 816 series was presented as the last modernization in February 2018 .
Conversions in Slovakia
commitment
The vehicles are approved for use in Germany and Austria. In cross-border local traffic, they were part of the daily routine at the border stations in Zittau , Ebersbach (Sachs) , Bad Schandau , Johanngeorgenstadt , Furth im Wald and Bayerisch Eisenstein . Until the timetable change in December 2006, they also came from Znojmo to Retz on schedule .
Despite the renovation program, there are still some vehicles that are largely in their original condition, apart from a partial modernization of the passenger compartment with new seating. They will continue to be used as planned on routes with little traffic. At the beginning of 2019 z. In the Moldava v Krušných horách train station , in the Chomutov train station , in the Rumburk train station or in the Stará Paka train station, bread boxes for operation on the branch lines can be observed. Some cars are also presented in the new Najbrt color scheme.
At the ČSD it was common to use sidecars of internal combustion engine railcars as locomotive-hauled passenger trains. The successors also retained this mode of operation.
