Te inicjały of te Beijing Subway are rooted in a unique historical context. Construction began in 1965 under a directive frem Mao Zedong, with the primary intence being military defense and civil defense rather than public transportation.

New lines were planned andd fast- tracked, including Line 5, Line 10, Line 8 (Olympic Branch), andhe Airport Express. By 2008, thee network had grown to ight linews and 200 kilometers, quading its sizen less thathan.

Expansion Strategies: The Planning Blueprint

Radial- Concentric Network Design

Te cory planning strategy for thee Beijing Subway is a radial- concentric model. The network factores a central loop line (Line 2) with radial lines extending extraard to thee contens and satellite tows. This design maximizes connectivity between thee city center andthee rapidly expanding districerery. New lines were notbuilt haphazardly and commerciont.
