The theoretical calculation of the whole journey is 1 hour and 20 minutes, but the actual operation is mainly due to the inaccurate bus time, so it should be no problem to arrive in 2 hours.

Bus route: Metro 13 → Metro Line 2 → 67, the whole journey is about14.5km..

1. Walk about 30 meters from exit B of Wudaokou subway station and arrive at Wudaokou station.

2. Take the subway 13 line, pass three stops and arrive at Xizhimen Station.

3. Walk about 240 meters and transfer to Metro Line 2.

4. Take Metro Line 2, pass 4 stops and arrive at Changchun Street Station.

5. Walk about 100 meters to Changchun Street West Station.

6. Take bus No.67, pass 1 station and arrive at Beijing West Railway Station (you can also take express buses No.2, 83, 90 1, 54, 9, 66 1, 662 and 209).

If I can help you, please "satisfy" below.
