China Railways CRH1 train set on the line reach a maximum speed of 220 kilometres per hour (140 mph) and make the full-trip in 30 minutes, before 2018. The line was built in 18 months and entered into operation on May 12, 2010. The railway is built to withstand an 8.0-magnitude earthquake. The Chengdu–Dujiangyan intercity railway has two branch lines: Pengzhou Branch line is 21.2 kilometres (13.2 mi) in length with 6 stations,[1] and Lidui Branch line is 6 kilometres (3.7 mi) in length with 3 stations.[2] In 2019, China Railways CRH6A-A (Tianfu) train sets on the line started to operate up to 200 kilometres per hour (120 mph).[3]

The railway runs from Chengdu railway station to Dujiangyan's Qingchengshan railway station and passes through Pidu District. Bridges and tunnels account for 67.8% of the line's total length. The longest viaduct is some 21 kilometres (13 mi). The line is built to withstand future earthquakes. Sound insulation panels were installed alongside the railway to reduce train noise near the tracks.[4] Clear panels allow passengers to enjoy rural scenery along this route.[4] The line shortened rail travel time from Chengdu to Dujiangyan by half, and will bring more tourist traffic to Dujiangyan's World Heritage Sites, the city's ancient irrigation system and Mount Qingcheng, a sacred Daoist mountain.

On May 28, 2008, 16 days after the Wenchuan earthquake devastated Dujiangyan and the western suburbs of Chengdu, the Chengdu city government and the Ministry of Railways agreed to build a high-speed railway line as part of the reconstruction of the disaster zone.[7] Construction began on November 4, 2008, and involved 20,000 workers at the cost of ¥13 billion.[4] The line entered trial operation on April 1, 2010, and full commercial operation began on May 12, 2010, the second anniversary of the large earthquake that killed some 70,000 people in the region.[4]
