Wuhan Metro Line 12 fully opened on October 29 in Wuhan, central China's Hubei Province. The 59.9-kilometer-long loop has 37 underground stations and takes about 96 minutes to complete a full circle, making it the longest of its kind in the country. It connects seven central districts and passes under the Yangtze River twice and the Han River once. The line also uses GoA4 fully automated trains, helping make cross-city travel faster and easier.
