The Beijing–Tianjin intercity railway (simplified Chinese: 京津城际铁路; traditional Chinese: 京津城際鐵路; pinyin: Jīng-Jīn chéngjì tiělù) is a Chinese high-speed railway that runs 117 km line (72.7 statute miles) between Beijing and Tianjin. Designed for passenger traffic only, the Chinese government built the line to accommodate trains traveling at a maximum speed of 350 km/h (217 mph), and currently carries CRH high-speed trains running speeds up to 350 km/h (217 mph) since August 2018.When the line opened on August 1, 2008, it set the record for the fastest conventional train service in the world by top speed, and reduced travel time between the two largest cities in northern China from 70 to 30 minutes. A second phase of construction extended this line from Tianjin to Yujiapu railway station in the Binhai New Area was opened on September 20, 2015.The line is projected to approach operating capacity in the first half of 2016. Anticipating this, a second parallel line, the Beijing–Binhai intercity railway, commenced construction on December 29, 2015. It will run from Beijing Sub-Center railway station to Binhai railway station via Baodi and Tianjin Binhai International Airport, along a new route to the northeast of the Beijing–Tianjin ICR.
