Technical features in brief

The 81-717 is a head car with a driver's cab, the 81 -714 is an intermediate car without a driver's cab. The 81-717 and 81 -714 are all-wheel drive motor cars.

The cars are designed for multiple-unit system use and are operational with a train of up to eight cars. The 81-717 cars are placed at the head and at the end of the train to make it suitable for shuttle work.

The design speed of the cars is 90 km/h, the number of seats is 44/40.

The car body is made of low-carbon steel and has an all-welded support frame. The outer coat is made of riffled steel plates providing better rigidness. The cars have improved sound and heat insulation.

The cars are fitted with two air conditioning systems, namely natural influx-and-extract ventilation and forced ventilation.

The cars are fitted with a DC electric tractive motors with smooth field regulation (motors excitation) designed for tractive and electrodynamic resistor slowdown (from 90 km/h to 8 km/h) modes. Every car is fitted with four 110 kW self-ventilated tractive motors, two for each bogie.

The car bogies are two-axial with frame suspension of tractive motors and pivotal suspension of reduction gears. The all-welded H-shaped frame has a two-stage spring suspension. The first-stage suspension is made up of spiral coiled springs. The second-stage swing suspension is also made up of spiral coiled springs and fitted with hydraulic shock absorbers for vertical and lateral oscillation.

The cars are to be fitted with the Minsk displayed speed systems (), radio station made in Belorussia, current collector, and FESTO (Germany) door pressure tubes with open/close delay mechanism.
