The 71-153 with energy-saving, fully computerized three-phase drive control has a low-floor area of 40% in the middle of its car body . There is a folding ramp for wheelchairs at the second door. The 71-153 is equipped with a passenger information system with LED displays and a digital radio intercom. A digital television system with two cameras and a TFT screen is available to the driver to monitor the passenger compartment and the non-visible space outside the vehicle. All information about the condition of the car is also displayed on the TFT screen. The 71-153 is a one-way vehicle and can only run on lines with reversing loops or triangles at the ends of the route.
