The Xi'an–Yan'an high-speed railway or Xiyan HSR (Chinese: 西延高速铁路; pinyin: Xīyán Gāosù Tiělù) is a high-speed railway line currently under construction in Shaanxi, China. It has a length of 299.8 kilometres (186.3 mi) and a maximum speed of 350 kilometres per hour (220 mph).[2] It is expected to reduce the journey time between Yan'an and Xi'an from 2.5 hours to approximately one hour.[3]
The railway is expected to open in 2025.[3] It will parallel the existing Xi'an–Yan'an railway, but take a more direct route.
