Tie Xi Qu: West of the Tracks is a 2003 Chinese documentary film by Wang Bing. Over 9 hours long, the film consists of three parts: "Rust," "Remnants" and "Rails."
Tie Xi Qu was filmed over the course of two years between 1999 and 2001 and details the slow decline of Shenyang's industrial Tiexi district, an area that was once a vibrant example of China's socialist economy. With the rise of the free market and the move towards other industries, however, the factories of Tiexi have all begun to be closed down and with them much of the district's worker-based infrastructure and social constructs.
Although Tie Xi Qu: West of the Tracks is rarely seen due to its length, many critics have named it one of the best and most important films of the 2000s.
