How long does it take from Beijing Capital Airport T3 to West Railway Station by Shuttle Bus line 7?

It usually takes around 2 hours. If there's a traffic jam on the road, it might takes 2.5 hours. I think this way is quite convenient and easy because you don't need to transfer many lines and cars to your destination.
If you want to take subway, you still need to take shuttle bus Line 3 to Dongzhimen Station firstly, then transfer to metro Line 2 to Xizhimen Station, and transfer to metro Line 4 to National Library Station, and transfer to metro Line 9 to BJ West Railway Station. It takes around 1.5 hours on the way.

Thank you very much Laurel! I'll take the Shuttle Bus
