Key advantages, car 71-153:

• Model 71-153 – four-axle car belongs to low floor tram-car lineup, produced by «PTMF» OJSC. The car-builders from St. Petersburg put cars of this model in serial production for the first time in 2008;

• This tram-car combines in itself both new and well-tried engineering solutions, components and materials that were successfully used in practice on tram-cars, model 71-152. In Saint Petersburg these cars function since 2007;
• Height of low floor in new series cars made by «PTMF» OJSC equals to 350mm;
• Low floor quantity in 71-153 – 40%;
• Two wide doorways and accumulation platform in the middle of low floor car’s area provide the fast passenger loading and unloading, as well as better comfort for passengers with push-carts, and for disabled persons;
• Compatibility is one of the new car’s advantages. Overall car length – 15 meters which enables the tram-car to harmonically negotiate the city traffic without making any additional hindrance for other road traffic participants;
• Exterior car’s design is provided with paste-in tinted  glazing,  which excludes any leakage and improves the car’s appearance;
• Outer and inner skin plating is manufactured from polymeric materials, which exclude possibility of corrosion onset and improve lifespan of the car’s body;
• New all-purpose car truck with two-stage cushioning and antivibration rubberized wheels (product of BonaTrans) allow to ensure the 750mm floor height above power truck, as against  900mm in previous generation tram-cars;
• The car is equipped with four asynchronous traction motors, powered 55 kW each, which enables the tram-car to accelerate up to 75 km/hr;
• At the same time, the modern electrodynamic brake system provides the installed stopping distance, under braking from maximum  service speed, without brake shoe wear;
• Besides, the car is equipped with anti-skidding and anti-slipping systems;
• For ensuring the continuity of service in traction equipment, tram-car is provided with pantograph having an electric drive (made by Lekov);
• The standard layout for passenger saloon implies  an arrangement of 19 to 31 sitting places. At that, the maximum passenger capacity equals 165 persons; 
• The car’s saloon is equipped with “lightning lines” on fluorescent tubes base, powerful electric air heaters for saloon heating and ventilating, with audio information “roll caption” displays, and door’s “target opening” system;
• The doors (product of Tamvere) have a fool-proof mechanism with anti-clamping function;
• The driver’s cab is made on computer-based automatic system with touch-sensitive display;
• The digital viewing system enables driver to control the situation inside the saloon and on the traffic way;
• The rear-view mirrors have a remote control drive and are equipped with electrical heater system;
• The adequate comfort and microclimate in a driver’s cabin are maintained by air conditioning system.
