Russian Subway Digital Display Upgrade Project

Russian Subway
Digital Display Upgrade Project

In March 2025, Gomany received an inquiry from Bauer Das, the manager of a Russian metro line. As the metro line manager, he oversaw a system with an average daily passenger flow exceeding 10,000. With increasing urban traffic pressure, he recognized the limitations of traditional display equipment and sought to introduce advanced digital signage to optimize passenger guidance and information management.

This collaboration stemmed from Bauer Das's in-depth research into Gomany's digital display products, particularly their successful use cases in the transportation sector. After numerous discussions and technical evaluations, Bauer Das and Gomany signed a cooperation agreement.

The project involved 300 metro stretched bar displays, 100 double-sided stretched LCDs, and 100 interactive digital signage kiosks. The Gomany team participated throughout the design and deployment process, ensuring seamless integration of the products into the Russian metro system. This collaboration gave Bauer Das' team confidence in digital transformation.

Difficulties And Solutions In The Cooperation Process

Difficulties

Space Adaptation Issues

Subway carriages have limited space and unique layouts. The installation of stretched bar displays requires precise adaptation. The screen must be stable without encroaching on passenger space. The screen also needs to be compatible with the carriage interior, placing high demands on the installation design.
Screen Durability Issues

The subway environment is complex, with heavy traffic, making digital screens susceptible to collisions and scratches. Furthermore, the subway's temperature and humidity fluctuate greatly, placing a severe test on the screen's durability. The screen's impact resistance, abrasion resistance, and environmental adaptability need to be improved.

Technical Integration Issues

Russian subway systems have unique interface standards, and the Gomany screen interface differs from them. To achieve seamless integration, a suitable interface adapter must be developed to ensure interoperability between the screen and the subway's signal transmission and control systems.

Gomany's Measures

Highly Customizable Screens

Gomany's design colleagues used data provided by Bauer Das to create precise renderings using 3D modeling technology. These pre-rendered images of the display installation scenarios were then used by engineers to adjust the frame material and structural design based on the model data, ensuring that each stretch screen perfectly fits the subway space.
Scene Simulation Testing

All devices utilize A+-grade OC panels and impact-resistant tempered glass. Prior to delivery, they undergo rigorous environmental testing. Gomany conducts tests in a laboratory simulating a subway environment, including continuous vibration, high and low temperature cycling, and humidity testing to ensure stable operation under these extreme conditions.
Customized Interface Adapters

Gomany's equipment utilizes multiple protocol interfaces, compatible with the metro line's various existing control systems, ensuring seamless integration of subway displays into existing information distribution and management systems.

Deficiencies In Existing Subway Operations

Poor Display Quality

Many subway stations still use traditional static signs or outdated LED displays, which are unable to provide real-time train information.

Over time, these signs have become difficult to read in dim underground environments and exhibit severe color distortion, making it difficult for passengers to obtain clear information about their journeys.
Aging Equipment and Frequent Failures

Many subway equipment is over 15 years old and has a high failure rate. Average monthly maintenance costs account for over 10% of the operating budget.

Bauer Das noted that in-car displays frequently go black, overwhelming the maintenance team. This not only increases the manpower burden but also poses potential safety risks, such as passenger confusion caused by information outages.
Inefficient Passenger Guidance

Bauer Das reported that unclear station directions often cause passengers to go to the wrong platform or miss their connections, impacting the overall efficiency of the subway system.

This results in hundreds of delays per month, and passenger satisfaction surveys indicate this issue accounts for as much as 25%.
Inadequate Emergency Response Capabilities

Bauer Das cited a past emergency incident where information lags caused platform congestion and significant safety vulnerabilities.

The lack of an integrated digital platform prevented linkage with central control, and emergency information was limited to scrolling on a limited number of LED screens, with coverage of less than 50%.

The Necessity Of Digital Upgrades For Subways

Real-time Information

Subways use digital screens to update train schedules, delay notices, and advertisements in real time, reducing information lag and shortening passenger wait times.

Bauer Das believes that using Gomany's display devices will optimize passenger flow and promote the development of smart transportation.
Intelligent Management

Upgraded subway equipment with digital displays now offers remote monitoring and intelligent dispatching capabilities.

Operators can monitor equipment status in real time and remotely control display content, enabling refined management and improving overall operational efficiency.
Enhanced Safety

Digital displays enhance emergency response mechanisms. Through highlighted alarms and multi-screen linkage, information coverage reaches over 95%.

Bauer Das stated that in evacuation scenarios, real-time notifications can guide passengers to take quick action and reduce the risk of accidents.

Main Applications Of Display Devices

Ultra Wide LCD Stretched Displays

Inside subway cars, stretched bar displays offer an ultra-wide field of view, showcasing train schedules, station information, public service announcements, and more.

Their high-definition image quality and smooth graphics provide passengers with a comfortable visual experience, enriching their journey.
Double-Sided Stretched Digital Signage

Double-sided stretched digital signage at platforms and passageways provides clear route navigation information to pedestrians in both directions.

The anti-glare design ensures clear readability in any lighting conditions, effectively guiding passenger flow.
Touch Screen Information Kiosk

The interactive digital signage kiosk integrates self-service ticket purchase and information inquiry.

Passengers can quickly purchase tickets according to the operating procedures, and can also query information about surrounding attractions, commercial facilities, etc. through the touch screen, reducing the pressure of manual service and improving service efficiency.

Comparison Before And After Subway Upgrade

Before the subway display upgrade, information updates were delayed, resulting in a 15% passenger complaint rate.

Peak ticket wait times reached up to 8 minutes, frequent equipment failures, high annual maintenance costs, and less than 50% emergency response coverage, leading to increased safety hazards and low overall operational efficiency.

Passenger satisfaction increased by 20%.

After the upgrade, real-time information push reduced complaints to 5%, and ticket purchase times to 2 minutes. System response speed increased by 68%, maintenance costs dropped by 25%, and passenger satisfaction increased by 20%.

The digital transformation has significantly optimized passenger flow, reduced perceived delays by 30%, achieved 100% safety alert coverage, and reduced accident risks. Bauer Das reports that intelligent management has saved over 40% of manpower on subway trunk lines.
