The "Green Line" refers to a public transportation system that operates in various cities, providing efficient and eco-friendly travel options. It is often part of a larger network of subways or light rail systems, designed to reduce traffic congestion and promote sustainable commuting. The Green Line typically features electric trains or trams that run on dedicated tracks, ensuring a smooth and reliable journey for passengers. In some contexts, the term "Green Line" can also refer to a specific boundary, such as the Green Line in Israel and Palestine, which marks the armistice borders established after the 1948 Arab-Israeli War. This line has significant historical and political implications, influencing discussions around territory and peace negotiations in the region.
