The number of single day passengers on Line 2 has exceeded 500,000 on Jan 1, 2013, the first weekday after its opening, excluding elders holding free passes.

To accommodate such huge traffic numbers, all stations on Line 2 have been extended to the length of 8-car trains for future use.

[9] An extension of the line to the south in Donghu New Technology Development Zone is operating and was opened on February 19, 2019.

[24] 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.

[25] 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.

A full train provides 176 seats, and can carry 1276 passengers by Chinese regulation of 9 people per square meter.
