The Ivolga 4.0 EMU made its inaugural run on the Line D4 of the Moscow Central Diameters (MCD) system on May 2, 2024.
Manufactured at the Tver Carriage Works (part of Transmashholding), the train features several key enhancements such as the third door in intermediate carriages – this addition, reminiscent of metro cars, enables faster passenger boarding and disembarking – it accelerates passenger flow by up to 30%. The new electric multiple unit provides an increased capacity compared to the existing train fleet, accommodating 100 more passengers, with a total capacity of 2,533 in an 11-car configuration. This is achieved through the addition of nine extra doors, creating more free space. The exterior design changes refer to the front of the train that has been redesigned with a darker and more streamlined appearance while for the interior upgrades, the headrests and handrails now feature a blackberry color scheme. The train provides convenient door opening button placement. Late-model Ivolga 3.0 trains and all Ivolga 4.0 trains have two door opening buttons located on either side of the door, enhancing accessibility.
The train’s driver’s cab has been designed to maximize comfort and safety. It has two-stage control system with 100% redundancy which ensures that two systems back each other up, allowing the train to continue operating normally even if the primary system fails. The train due to its rapid turnaround, the train can change direction in just one minute, reducing dwell time at terminal stations and improving service frequency. The train it equipped with enhanced information display with diagnostic data and train performance information that are now displayed on two screens instead of one, giving the driver a more comprehensive view. The Ivolga 4.0 EMU is also fitted with surveillance system comprising closed-circuit cameras that provide the driver with visibility inside and around the train, with all footage transmitted to the control panel. The driver also benefits from ergonomic and adjustable seats and the assistant ensure comfort and quick response times. The cab includes a cooled cup holder and electronic card access for faster and more secure entry.
The train’s production involved the collaboration of approximately 50,000 employees from 600 enterprises across Russia. It highlights Moscow’s role as a major driving force in the country’s transport engineering sector, as the city accounts for 75% of all transport machine-building orders in Russia. According to Maksim Liksutov, Deputy Mayor of Moscow for Transport, without these orders spanning three to five years, Russia’s transport engineering sector would not have reached its current level of development.
“The development of the MCD is a top priority for the city. This year, we will introduce 53 modern trains on the new diameters. By the end of 2024, we plan to update the rolling stock on long-distance commuter routes on the Line D3. And on D4, we will complete the replacement of trains by the end of 2025. The new Ivolgas will make travel even more comfortable. The production of these trains not only improves the city’s transport system but also contributes to the development of the domestic machine-building industry,” Maksim Liksutov said.
Moscow continues to invest in replacing outdated trains with modern, state-of-the-art models. Since 2011, the share of updated rolling stock in the entire Central Transport Hub has increased almost 15-fold, from 5% to 71%. The average age of the rolling stock has decreased by a factor of 3, from 24 to 8 years. The share of intra-city trips by rail has almost doubled.
