At the same time, the Shenzhen-Huizhou Intercity Railway has also added a Dapeng branch line with its terminal at Xinda station, which to a certain extent replaced the Kuichong-Xinda section of the line; this line has also been changed to a horizontal connection line and the distance has been greatly reduced.[4]
