(2/2) 17:41 Takadano-Baba Sta. 25:14 Two Plans ABOUT THIS VIDEO Shinjuku Station is world-renowned as a massive "dungeon," but Seibu-Shinjuku Station stands notoriously apart from the main JR and subway hubs. Why is it so far away? This video explores the fascinating history of the Seibu Shinjuku Line, from its origins as the Kawagoe Railway to the postwar maneuvers that led to its current "isolated" terminal. We dive into the "phantom" extension plan to the Lumine Est building, the unique 11-car platform doors at Takadano-Baba Station designed to manage extreme congestion, and the failed multi-billion yen deep-underground quadruple-tracking project. Finally, we look at the future: the newly announced underground passage project set to slash transfer times to the Marunouchi Line by half, finally bridging the gap that has inconvenienced commuters for over 70 years. ●WHAT YOU WILL LEARN The historical reason why Seibu-Shinjuku Station ended up 700m away from the main Shinjuku hub Inside the unrealized plan to bring Seibu trains directly into the Shinjuku Station building Why Takadano-Baba Station, not Seibu-Shinjuku, is the true functional heart of the line with 1.8x more passengers The secret of the "extra-long" platform screen doors and special signaling at Takadano-Baba used to battle morning rush hour How the postwar "Railway Regiment" practice lines and Keisei Electric Railway influenced Seibu's expansion The technical and financial "double punch" that killed the ambitious 60m-deep underground quadruple-tracking plan The "0km post" anomaly: Why the start of the Shinjuku Line is officially located at Takadano-Baba instead of the terminal Details of the upcoming 2025 redevelopment project and the new underground shortcut to the Marunouchi Line A look inside the Limited Express Koedo and the operational quirks of the 10000 series "New Red Arrow" ABOUT THIS CHANNEL Welcome!
