81-765/766/767 “Moskva” (Moscow)

81-765/766/767 “Moscow” is a model of subway car used on the Moscow Metro, Tashkent Metro, Baku Metro and the Minsk Metro (planned). It was designed by Metrowagonmash and is manufactured by Metrovagonmash and Oktyabrsky Electric Repair Plant (OEVRZ). Actually, the train serves in the Moscow Metro, Baku Metro, Tashkent Metro and Minsk Metro (in plans).

The body of the wagons “Moskva” served as the basis for other models. In particular, the train «Baltiyets» (81-725.1/726.1/727.1) for the St. Petersburg metro and the train «Moskva-2020» for the Moscow Metro.

Design

Cars 81-765/766/767 are a further improvement of the «Oka» (81-760/761/763) modifications A and B with a through passage. Their main differences from their predecessors are a new driver’s cab mask, increased width of entrance doors and reduced width of windows, a slightly reduced number of seats in the cabin in favor of increasing capacity, an improved interactive passenger information system, and more modern and compact electrical equipment. The traction and auxiliary equipment of the train is placed more evenly, due to which the eight-car train has become 22 tons lighter in comparison with cars of types 81-717/714 and creates less load on the track.

General information

Cars of models 81-765/766/767 “Moskva” are designed for passenger transportation on metro lines with a gauge of 1520 mm, electrified by a side contact rail with a voltage of 750 V DC. Trains can be operated on both underground and above-ground sections of lines.

The cost of one new car of the Moskva train is 65 million rubles. The estimated service life of the cars is at least 30 years.

Interior

The sofas are located between the doorways on each side of the carriage and consist of six separate seats each. The exception is the first sofa on the right side in the head car: it consists of three seats closer to the middle of the car, and the remaining space is occupied by a storage area. It increases the capacity of the carriage and also allows you to accommodate large luggage, wheelchairs and baby strollers. For the convenience of disabled passengers, the platform is equipped with a vertical blue backrest and straps for securing wheelchairs. Similar platforms were previously used in the «Yubileiny» (81-722.1) metro cars.

In modification .2 trains, the seat layout in the head cars differs from the base model and is combined, similar to the modernized metro electric trains 81-71M. The number of seats in the areas between the doors has been reduced from six to five on each side of the aisle, with only the outer seats on each side of the windows facing the aisle, while the seats opposite the windows face along the direction of travel towards the middle of the window and are placed at a 2+1 and 1+2 scheme, with the seats in the middle and rear having central cross symmetry. In the head part between the first and second doors along the left side, both transverse seats opposite the window are double, and on the starboard side there is only one transverse and one longitudinal seat closer to the second door (8 seats in total). In intermediate cars, the layout of seats has not changed, however, in trailer car 81-767.2, the seats on the leftmost of the three sofas relative to each side are folding.

Trains of modification .3 differ slightly from the basic modification by the presence of fabric seat upholstery, as well as a modified location of information displays. Trains of the .4 and .4K modifications are equipped with new overhead displays with high-definition screens, modified handrails have been installed (a ceiling handrail has appeared), the color of the floor and doors on the inside has been changed from blue to gray in two tones (darker in front of the seats and lighter in front of the doors.

Composition

Electric trains are generally formed from three types of cars: two head motor cars (Mg) 81-765, up to four intermediate motor cars (Mp) 81-766 and up to two intermediate trailed cars (Pp) 81-767.

The minimum number of cars in a train is two (head cars only), the maximum is eight (two head cars, four intermediate motor cars and two intermediate trailer cars (non-motor cars)).

Eight-car trains for the Moscow Metro (basic model, modifications .3 and .4) are formed according to the scheme Mg+Mp+Pp+Mp+Mp+Pp+Mp+Mg, that is, trailer cars are third in a row at both ends of the train. On the Filevskaya line, trains of modification .2 are operated in a six-car design according to the Mg+Mp+Pp+Mp+Mp+Mg scheme, that is, with one intermediate trailer car.

Trains of modification .B for the Baku Metro in a five-car design are formed according to the Mg+Mp+Mp+Mp+Mg scheme, that is, without trailer cars.

Trains of modification .5 for the Tashkent metro in four-car design are formed according to the Mg+Mp+Pp+Mg scheme with one trailed car, and trains of modification .4K for the Kazan metro are formed according to the scheme Mg+Mp+Mp+Mg (without trailed cars).
