The Yan'an Road Medium Capacity Bus Transit System (Chinese: 延安路中运量; pinyin: Yán'ān lù zhōng yùn liàng) is a bus rapid transit system operating within Shanghai, China.

[2] It reused the route number 71, which followed a similar path from Huangpu to Changning districts along Yan'an Road.

[4] In May 2017, the operator noted that it was considering the possibility of using buses with doors on both sides in order to allow commuters to seamlessly transfer to route 71.

[6] The buses feature a silver body, a black-painted front and red stripes running through the fuselage.

They are equipped with a wheelchair bay and LCD passenger information display, with announcement systems in Standard Chinese, Shanghainese and English.

[14] This is a list of stations along the Yan'an Road Medium Capacity Bus Transit System.

It was reported in 2015 that at one point, the number of complaints regarding the cancellation of route 127 to the service hotline of the bus operator reached over 300 within a few days.

[18] This is in spite of the designated bus lane, which was frequently obstructed by jaywalkers and vehicles running red lights.
