Stations

Change of Names 
On August 23, 2012, five stations were renamed according to the result of a poll.
Jinse Yayuan and Mingdu Stations were firstly named after nearby real estate development, and was subsequently renamed as "Changgang Road" and "Yangjiawan" respectively to avoid advertising for the development.
"Hankou Railway Station Station" has been renamed "Hankou Railway Station" to avoid unnecessary repetition and pronunciation challenges.
"Jia" in Pangxiejia has a homophone that tells the story of history as the site of Metro station was once a section of the ancient city walls of Wuchang that were built along the Pangxiejia ridge.
"Xiaoguishan" replaced Tiyu South Road (Tiyunanlu) to make the historical places more easily recognizable.

Paired Cross-Platform Transfer 

Hongshan Square station and Zhongnan Road station offer paired cross-platform interchange for passengers riding between 4 directions of the two lines. The configuration for the two stations is similar to that of Mong Kok and Prince Edward stations in Hong Kong's Mass Transit Railway.

Passengers riding on Line 2 from Hankou wishing to reach Wuchang railway station, can transfer at Zhongnan Road station by crossing the platform. Those who going to Wuhan railway station, can transfer at Hongshan Square station by crossing the platform, and vice versa.

Stations of Line 2 provides female only waiting area during hours of operation, following the example of Tokyo, Osaka, Nagoya, Tehran and Mexico City, to protect female riders from sexual harassment. Wuhan became the first city to set up female only waiting area in China.

Starbucks Metro Store 
China's first Starbucks Metro store is opened in Hongshan Square station.

Sale of Partial Naming Rights 
Partial naming rights of Jianghan Road station of this line was sold to a local snack producer, Zhouheiya (Zhou's dark duck), and has aroused public discontent with the Wuhan Metro Group company. Some are upset by the fact that Metro company sold the rights without public input; some are because the product is not of high taste, and might affect the image of the city; some think it is fine, for selling partial naming rights is a good way to attract funding from the private sector, and does not materially affect the quality of the service.

As of November 23, 2012, all sale of partial naming rights are canceled.
