According to the terms of the contract, the first electric locomotive will be delivered to the customer by March, the second by May 2022. The locomotives are purchased as part of the program to renew the fleet of special rolling stock of the St. Petersburg Metro for 2020–2025.

Contact-battery electric locomotives (ECA) operate on electric motors, which can be charged both from batteries and from the contact network. This technique is used in the metro in situations when there is no voltage in the contact network. A battery electric locomotive can also be operated for shunting operations or as part of a utility train.

The structure of the rolling stock is based on the body of the metro car 81-714 and will have two control cabins. In place of the passenger compartment there is a battery compartment. The electric locomotives will also be equipped with video surveillance systems. The rolling stock is equipped with bogies with a reinforced frame.

Electric locomotive characteristics:

  • nominal capacity of traction storage batteries – 1000 A/h;
  • design speed – 90 km/h;
  • service life – 50 years.
