Beijing Public Bus Services
In 2015, the entire public bus network in Beijing consisted of 876 routes with a fleet of 24,347 buses and trolleybuses carrying 3.98 billion passengers. Trolleybuses ran on over 25 routes, many of which are located inside the Third Ring Road and some extending as far out as the Fifth Ring Road. In an effort to reduce urban air pollution, the city has been converting regular bus routes to trolleybus routes by installing overhead power lines on several corridors since 2013.
The network is run by two operators today. The city's primary public bus operator, the state-owned Beijing Public Transport Holdings, Ltd. operates most routes, and an independent operator provides service on 31 "Yuntong" ( 运通 ) bus routes. The bus fare of both companies begin at two yuan and are subject to a 50 percent discount when purchased with the mass transit IC card (‘Yikatong'), which effectively lowers the cost of most bus rides in the city proper to one yuan.
Trolley bus service opened in Beijing in 1959, leaving the tramcar rails a thing of the past.
