I will arrive Beijing west railway station to visit Geat wall. Is it nearby from this area? Sabu,

The Great Wall is far from the West Station. You can choose to take the bus No. Te 13 to Deshengmen first and then take Bus No. 919 to Badaling. Or you can choose to go to BJ North Station first and then take a train to Badaling. You can take bus No. 694/387/21
and get off at South Xizhimen Station, and walk to the North Station. There are S-types available from BJ North to Badaling.
