Characteristic properties, car model 71-152:

This car has more than 60% of low floor, two doorways are equipped with pullout access ramps for wheelchairs ascent and descent;

Traction electric drive is made on the modern base and provides better energy and dynamic properties: increased performance coefficient, fast operating speed, more smooth acceleration and deceleration;
Asynchronous traction motors are in use, which have lesser mass-parameter characteristics, more reliable in operation and simple in maintenance, than direct-current motors;
At braking mode provided capability of recuperation into supply power;
Has integrated equipment diagnostic system enabling the prompt control over all the elements by the driver;
Anti-vandal seats are installed in car’s saloon;
Driver-s cabin is made in accordance with modern ergonomic requirements;
Cars have modern original interior;
Complex digital data system is installed, comprising autoinformator, loudspeaker communication, route indicators, information board (roll captions type)
Hind part with low floor level is equipped with access ramp for wheelchairs ascent and descent.
