Lot 2 of Stage II "h.c. Mladost I - Mladost III - bul. Tsarigradsko Shosse" (put in operation on 25.04.2012)

The main executor of the section was "Merged Enterprise Metro Mladost", value of the contract: 221 970 879.60 BGN including VAT. The equipment is from leading companies in the field, such as Siemens, Thyssen, Ericsson, Aerfol, Transavtomatika and others.

Information about the new trains:

The delivery of the trains is carryng out under Stage II of the "Project for the extension of the Sofia Metro", which is in execution  under Operational Programme "Transport" with funding from the Cohesion Fund of European Union, with local co-financing.

The value of the contract is worth 153 846 000 BGN, without VAT.

According to the supply contract, until the end of November 2012, 18 metro trains, each of 1100 passengers capacity, must be delivered. Some of them have already been put into operation.

The delivery is on schedule, and a number of trains already transport passengers approximately one month. All the equipment from the main contractor of the manufacturer - the Japanese company "Hitachi" was produced and delivered earlier than expected, what provided for the timely completion of the contract.

The trains are co-production of “Metrovagonmash”SC and JSC “Hitachi”. The body (the compartments) of the wagons and the bogies with the wheels and wheel’s axis are production of “Metrovagonmash”, while the motors, power electronics and control and command systems are produced by the Japanese company Hitachi. The electric motors are of asynchronous type with recuperation (recovery) of energy in the metro power system during the time of coasting and braking mode, i.e. in these cases they work as current generators. As a result, the expense of energy they have is about 25% less than it is spent on trains with conventional engines.

The body of the wagons is made of stainless steel, and therefore it is corrosion resistant and has longer life. The train is equipped with appropriate modern anti-skid devices, lubricators to lubricate bandages as to have them less worn-out, auto-lock system, automatic speed control and more.

Results in case of successful implementation of Stage II:

- Built subway lines - 6.7 km;

- Built metro stations- 6 pcs;

- Number of realized new trips on the subway system - 92 460;
