Abstract：Research purposes: There are lots of passengers staying in the railway station building in where there are the power supply and distribution systems，the building intelligent systems and the transportation dispatching systems and the communication and signal systems． In order to guarantee the safeties of the personnels，facilities and transportation production， the protection of direct lightning flash and lightning electromagnetic impulses ( LEMP) must be well done for the station building． The earthing for lightning is systematacially studied in this paper and the key points of design are presented．
Research conclusions: From the the analysis it is concluded ( 1) The external lightning protection should be used along with the internal lightning protection for the lighting protection for station building． ( 2) The equivalent potential bonding is the most critical measure for lightning protection． ( 3) The comprehensive earthing requirements of 1 ohm has not to be meet by every building．
