Construction of the Xiashen Line commenced in November 2007 and the line was initially expected to open in 2011. But the anticipated completion was repeatedly delayed due to further safety reviews and inspections after the Wenzhou High-Speed rail crash. In December 2012, the anticipated opening date was pushed to October 2013. Test runs did not commence until November 2013. The line officially opened on December 28, 2013 with trains running from Shenzhen North to Shanghai Hongqiao.
