Oak Bay is called double-track property. What does double-track property mean?

Oak Bay's transportation network extends in all directions, and Old Town Pass Road, Shaxi Line, Yangxi Line, IT Avenue and Ring Expressway are all convenient for travel. The high-speed railway is now open to traffic. Hong Guang Station is 700 meters away from Oak Bay. Metro Line 2 is this blue light belt. You can transfer to the subway at the same station after the Hongguang Zuokuai Railway arrives at Xipu Station and take a bus ferry to and from the subway station. In this way, it is very convenient to go shopping in the city or to spend the summer in Qingcheng Mountain. The bus ride time is about 15 minutes, which is a "double-track property".
