Kulbanetunnelen

Slipping beneath Kulbanevej, the Kulbanetunnelen whispers secrets of a city’s evolution. This 700-meter double-track railway tunnel isn’t just a conduit for trains. It’s a testament to Copenhagen’s commitment to preserving its green spaces and the tranquility of its residents. Kulbanetunnelen, completed in 2017, carries the Ringstedbanen line, connecting Copenhagen to Ringsted via Køge Nord. Interestingly, it was finished two years before the line opened due to delays in other parts of the project. Above the tunnel, Kulbanevej, a park, and Vigerslevvej bridge create a vibrant urban tapestry. Kulbanetunnelen’s primary purpose was noise reduction for the residential areas of Vigerslev Vænge and Hornemanns Vænge. It also maintains the crucial green corridor between these neighborhoods. Built using the cut-and-cover method, Kulbanetunnelen boasts a ventilation system. It’s not needed for daily operation due to the tunnel’s short length. But it’s vital for smoke extraction in case of a fire. Emergency sidewalks on both sides of the track ensure safe evacuation. Kulbanetunnelen accommodates both electric and diesel trains, serving both passengers and freight. A curious fact: the tunnel lies a mere few hundred meters from the shorter Hvidovretunnelen. While the latter curves differently, the two tunnels are technically identical. Kulbanetunnelen’s name derives from Kulbanevej, which itself is named after a former railway that served the Valby Gasworks. This older railway once occupied the same area. So, while the Ringstedbanen runs through Kulbanetunnelen, the tunnel’s name harkens back to a different railway entirely. It’s a quiet reminder of the layers of history embedded within Copenhagen’s modern landscape.
