Line 2 runs in a northwest-southeast direction, connecting Hankou and Wuchang, including Hankou Railway Station and major commercial districts. 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. When more lines interchangeable with Line 2 open around 2015, the passenger volume could reach 1 million per day. To accommodate such huge traffic, all stations on Line 2 have been extended to the length of 8-car trains for future use.
Line 2 might be the most important metro line in the Wuhan Metro system for being able to carry the heavy cross-Yangtze traffic in Wuhan.
