Cause of this, it's the one of the busiest railroad lines in China. A completely new line had been started to build near of it. It's called Beijing- Harbin High Speed Railway. It'll also through the same cities what I said. The difference between two is speed. The quickest speed of the high railroad line is about 350 kilometers an hour.The section of it which is from Harbin to Shenyang had been used since December 2012, the section which is from Beijing to Shenyang had just started to build since 2014. The whole high speed railroad line will be used after 4 or 5 years, between 2018 and 2020. Another important main railroad line is Shenyang-Dalian Railway. It was built by Russian since 1898 to 1903.

Finally, they were successful . Harbin- Manzhouli Railway and Harbin-Suifenhe are the sections of the branch line.At the beginning, Russian completely controlled them and got a lot benefits.
