Second Xiangyu line
The second Xiangfan–Chongqing railway () is a dual-track electrified railroad line that runs parallel to the Xiangyu line. This line is only 507 km in length and connects the same cities as the original Xiangyu line. It takes a more direct route through the mountainous terrain with bridges and tunnels, and accommodates faster trains (up to 160 km/h) and a greater carrying capacity. Construction began on August 13, 2005. and was scheduled to be completed by July 2008, but work was slowed by difficulties in bridge and tunnel work which pushed the project 30% over budget. The New Iron Mountain Tunnel (), 3,347 m length, was completed on April 20, 2007 after 20 months of difficult work, overcoming interior rockslides and carbon monoxide build-up inside the tunnel. The second Xiangyu line opened on October 31, 2009. ==Rail junctions==
Painting of the Xiangyu line
The Xiangyu line is the subject of an enormous landscape scroll painting that is 1.6 m wide and 128 m long. It was completed by Yang Migui in May 2008 who was a worker on the line's construction in the 1970s, and began working on the painting in 1998. It is reportedly the world's longest painting created by a single artist. ==See also==
