Xiongjing Metro

The Xiongjing Metro is a rapid transit system serving Xiongjing, capital of the Bai Empire. Operated by the state-run Xiongjing Urban Transport Authority (XUTA), the 12-line metro network spans the capital, complemented by a small number of light rail networks localised in certain areas of the city. At 460 km, it is one of the longest metro networks in the world and has an average of 5.7 million daily ridership as of 2020.

At the beginning of the 20th century, the Xiongjing City Government commissioned a study for an underground transit system in the city. The first segment of the metro from Hongxun to Zhongshichezhan opened on 10 November 1912. Expansion works continued during the Fascist Era, before slowing down as the city went into great debt during and after the War of Fellow Brothers. Under the Regent Era, the network started to grow swiftly in accordance with Yu Zeming's plans to redevelop the capital.

While the metro is being expanded, renewal works are regularly carried out to ensure the continued reliability, accessibility and safety of the network. All stations have platform screen doors, Wi-Fi connectivity, lifts and climate control. As of 2020, the total operational expenditure amounted to 40.2 billion yuan. Much of the operational expenditure is covered by passenger fares. To ease payments on the public transport network, the Xiongjing Metro adopted BaiPass in 1987 and has accepted contactless bank payments since 2016.
