The vehicles of the series SM 488.0 (today series 560 ) are electric multiple units for regional traffic of the former Czechoslovak State Railways (ČSD) on the 25 kV 50 Hz alternating current network.
history
The development of these AC multiple units and the subsequent ČSD series EM 488.0 goes back to 1962, when the Ministry of Transport of Czechoslovakia placed the order for two prototypes. In the course of development and production, the requirements were specified several times; the ministry demanded an increase in the maximum speed, multiple control and the replacement of the cam switch mechanism by a circuit with a thyristor .
The Vagonka Tatra in Studénka and the MEZ Vsetín produced two prototypes in 1966 as a three-part unit with the designation SM 487.0 . It consisted of a railcar, an intermediate car and a control car. Very soon it turned out that this unit was not enough, and so in 1970/1971 the units were designed with three sidecars and one railcar at each tip.
technical features
The vehicles are designed as large vehicles. The railcars have an open-plan compartment and a baggage compartment, the intermediate cars have two open-plan compartments and two end entry areas as well as a central entry which is equipped as a double-door entry.
The car body is a self-supporting welded steel construction. The bogies are arranged at each end, connected by a pivot pin. In the railcar, four traction motors are suspended lengthways under the vehicle floor, which transmit the torque to the axles via the cardan shaft and axle drive. The vehicles' braking system consists of a handbrake, a direct pneumatic brake for the railcars and an indirect pneumatic brake for the entire train. Each bogie has a brake cylinder with a diameter of 14 ". All wheels are braked on both sides with a block brake.
There are a total of four pantographs on the roofs of the railcars . The front pantograph of the ŽSR was later dismantled due to a lack of demand. The traction converter is located under the floor approximately in the middle of the railcar. It has the designation LTS 1.3 and is oil-cooled. The current for the traction motors is controlled by a rectifier with thyristor control. The traction motors are six-pole serial DC traction motors. The vehicles are equipped with an electrodynamic brake. It originally consisted of one stage, after the reconstruction of two stages and works in the range of 20 km / h to 110 km / h.
Unlike the old 451 series , which is equipped with a Scharfenberg coupling , this unit was designed with a conventional screw coupling and buffers.
commitment
The multiple units are still in use at ČD and ŽSR . The vehicles are used in S-Bahn- like transport in the metropolitan areas around Brno , Bratislava and Trnava . The units used in Brno are even deployed in six parts.
