OEVRZ sent to St.Petersburg the last car of a six-tram batch


Oktyabrsky Electric Car Repair Plant (St.Petersburg, an entity of Transmashholding, JSC) shipped to St. Petersburg operator Gorelectrotrans a class LM-68M3 tram, the last delivery of a six-tram batch that underwent overhaul reconditioning and in-depth modernization. 

The overhauled trams were built by Leningradsky Tram Plant at the end of 1991 and since had been operated in Saint Petersburg. They represent one of a tram car model most widly used in the northern Capital of Russia. Gorelectrotrans awarded OEVRZ a tram overhaul contract in the spring of 2015. 

The modernization process was aimed at the improvement of tram esthetics, enhancement of its ergonomics, operational performance and cost of operation, and reduction of noise emission. The traction drive system integrating asynchronous motors is a significant contribution into electric power consumption savings (24 to 40%). Overall reduction of operational costs is estimated at 30%. 

Alongside with attractive appearance, the refurbished trams feature lowfloor area for physically challenged passengers, wide passenger doors (1,450 mm), door anti-jam system, saloon fiberglass paneling, smoked safe glass windows, passenger seats with rubber coating and soft filler, and up-to-date information system. The tram has radio communication, audio and light signalling, and video surveillance system. The sitting configuration of a car offers two rows of soft seats. 

The refurbishment operations included complete redressing of passenger saloons, replacement of electric equipment and bogies upgrade. The overhauled tram cars got new carbodies with steel welded body frame, sheathed with composite plates. As per customer request, the tram received passenger doors on both sides of the car. The upgraded trams may operate in multiple unit mode achievable in two versions – traditional unidirectional tram-train or bidirectional tram-train made of back-to-back coupled trams for operation on lines without turn-around points. A second rebuild contract is now being realized by OEVRZ, and this will result in nine more class LM-68M3 trams. These are scheduled to be returned to the customer by the end of 2016.
