Query on Shen Zhen Bei Zhan on Longhua line, SZ Metro

I am traveling to Changsha by Fast train(Guo Tia) from SZ North Railway station. Is SZ North Railway station the same as SZ Bei Zhan on the SZ Metro Longhua line?
Why is there no times in your article (and on SZMC.net) for first and last train departing SZ Bei Zhan to and from Fu Tian Kou An metro station? Does the metro train, Longhua Line actually stop at SZ Bei Zhan from/to Fu Tian Kou An station?
Thanks for your help
