Gangdong-gu, located in the eastern part of Seoul, South Korea, is a rapidly developing district that combines residential, commercial, and greenbelt areas. Despite its growth, the area has long suffered from limited transportation infrastructure. While Seoul Subway Line 5 and Line 9 partially serve Gangdong-gu, residents still experience inconvenient east-west travel and serious congestion during rush hour.
To address these issues, the Seoul Metropolitan Government and Gangdong-gu Office have proposed the introduction of a modern tram system. As planning becomes more detailed, the project is drawing keen interest from both the public and urban planning professionals.
However, trams are still a relatively unfamiliar form of public transit in Korea. Many people ask, “Why a tram now?” and “Aren’t electric buses good enough?”
This article explores the urban significance, pros and cons, and the potential transformation that the tram could bring to Gangdong-gu.
What Is a Tram?
A tram, also known as a streetcar, is a rail vehicle that runs on tracks embedded in city streets and is powered by electricity. Unlike subways, trams don't require extensive underground construction, and unlike buses, they operate on fixed routes, ensuring predictable, on-time service.
Trams are widely regarded as eco-friendly urban transit solutions that help reduce air pollution and carbon emissions.
Their quiet, smooth operation and sleek design also contribute to enhancing urban aesthetics and quality of life.
Tram vs. Electric Bus: What's the Difference?
People often ask: “Why invest in a tram system when we already have electric buses?” It's a valid question. Electric buses are flexible and inexpensive to introduce, making them suitable for small-scale needs.
However, trams offer advantages that electric buses cannot easily match:
- Reliable, fixed routes: Trams run at predictable intervals and locations, creating greater trust and usage consistency among passengers.
- Higher passenger capacity: A single tram unit can carry 150 to 250 people, while electric buses typically accommodate 60 to 70 passengers.
- No battery replacement issues: Trams draw continuous power from overhead lines, eliminating the cost and logistics of battery replacement.
- Urban regeneration effects: Tram projects are often linked with sidewalk improvements, green spaces, and urban beautification—something electric buses alone cannot provide.
The Tram as a Catalyst for Urban Renewal
Trams are more than just vehicles; they are urban transformation tools that reshape space and behavior in the city.
1. Transition to Walkable Streets
Trams encourage walkability by slowing down traffic and promoting people-oriented urban planning. Tram stations often become hubs for plazas, cafés, and cultural areas.
2. Revitalization of Local Businesses
Because trams stop at fixed intervals, they draw foot traffic to specific areas, offering economic opportunities to small businesses and increasing commercial activity. Cities like Strasbourg (France) and Freiburg (Germany) have successfully revitalized old districts following tram installations.
3. Increased Residential Value
Tram-connected areas tend to enjoy increased accessibility and livability, leading to a rise in housing demand and property values. In Gangdong-gu’s case, neighborhoods like Godeok and Gangil, which are part of ongoing urban development, could particularly benefit.
Why Will Car Traffic Decrease?
Studies have shown that car usage declines in areas with well-integrated tram systems. Here's why:
- Trams offer punctual, congestion-free transport, making them more attractive than personal cars during peak hours.
- Tram projects often include car-restrictive policies such as limited parking, pedestrian-priority streets, and fewer car lanes.
- Tram + walking becomes a practical option for short- and medium-distance travel, reducing the need for cars.
Challenges and Drawbacks of Trams
Despite their advantages, trams are not without challenges:
- High initial construction costs and long project timelines can disrupt traffic and trigger public complaints during the building phase.
- Low route flexibility: Unlike buses, trams can't easily be rerouted during emergencies or roadworks.
- Reduced car lanes and traffic congestion risk: Trams take up road space, which may slow down other traffic if not properly planned.
- Demand uncertainty: If passenger numbers fall below expectations, operational deficits may occur, causing political and financial concerns.
Gangdong-gu’s Tram: A New Beginning for Seoul’s Transit?
Gangdong-gu continues to grow and evolve, and the proposed tram could serve as more than just a transportation tool—it could be a symbol of Seoul’s shift toward sustainability and quality urban life.
To succeed, the tram system must integrate seamlessly with existing transportation networks, prioritize pedestrian experience, and earn public support through communication and thoughtful planning.
In Conclusion
Trams are not just “streetcars”—they are strategic urban devices that can unlock new possibilities for cities. If Gangdong-gu’s tram project is successful, it could pave the way for other districts and potentially reshape Seoul’s entire transportation philosophy.
As Seoul looks toward a greener, more people-centered future, this “silent steel” may mark the first strong step on the path to real transformation.
