TMH will refurbish 40 more metro cars for Sofia


Metrowagonmash (MWM, part of TMH) and Sofia Metro signed a contract amendment to refurbish and modernize an additional batch of 40 Series 81-717.4/714.4 metro cars.

The contract for modernization of the first eight Series 81-717.4/714.4 metro cars, with a possible option for 40 more, was signed in December 2018. In February 2020, the core of the contract was fulfilled, and the eight metro cars were shipped to the customer. The amendment covering the option was signed in March 2020.

This type of contract provides the customer with the right to increase the purchase quantity while retaining the conditions. A call for the option indicates a positive evaluation of the contract’s core from Sofia Metro.

The project will be split into three phases: the first and the second phases involve modernization of three 4-car trains each (24 cars total), and the third phase includes four 4-car trains (16 cars). Each phase will take up to 12 months. Considering the load on the transit network caused by the trains withdrawn from service for modernization, the manufacturer will do everything possible to shorten the turnaround times while retaining the maximum quality.

The refurbishment and modernization will affect most equipment, the exterior, and the interior of the trains. As such, the trains will have new wheelsets with anti-skid protection, new coupling mechanisms, fire safety compliant trim materials, injury-free windows, new comfortable seats, smoke detectors, temperature sensors, LED information displays, and warm-to-touch handrails. The head cars will feature accessibility zones.

The Bulgaria’s capital metro will receive modern metro cars with fresh equipment and updated exterior. This will improve the passenger experience, reduce operational costs, and ease up the maintenance. The refurbishment will extend the lifecycle of the machines by 15 years.

Sofia Metro and MWM remain partners since its inauguration in 1998. Today, its entire fleet is made in Russia, and amounts to 168 units. Over a quarter of the fleet will be refurbished as a result of the option contract.
