3. Petr SýkoraV13 From trhe passenger view 61 sitting places 239 standing places – 8 persons/m 3 1 place for baby car or disabled person High of floor above platform: 350 mm/450mm, without steps- low floor 100% v max 60 km/h

4. Petr SýkoraV14 Mechanics Car length 31400 mm Car width 2460 mm Car high 3600mm Rotary bogie type Jacobs. That means under section link Rotary sections Uspořádání pojezdu Bo´Bo´Bo´Bo´

5. Petr SýkoraV15 Bogie Free wheels –Wheels are not connected with shaft –The space for shafts is used for low floor –Good driving features in curves

6. Petr SýkoraV16 Brakes Electro dynamic brakes recovering or into resistances –Main brake Electrohydraulic brakes with disks directly on Wheels –Park and emergency brake –The pressing forth is performed by spring. Releasing is performed with hydraulic Elektromagnetic friction rail brake. _supplied from battery _Emergency

7. Petr SýkoraV17 Drive Every wheel is driven separatly by a tgraction motor TM is situated crosswise in the bogie No gear box. Wheel is directly driven. Between wheel and traction motor is a short elastic clutch

8. Petr SýkoraV18 Electric equipment 4 bogies whith 4 synchronnous TM each. 16 TM and 16 invertors with IGBT. Convertor for auxiliary drives and battery charging Battery Everything is on the roof.
