Full-scale　experiment　is　an　important　method　for　fire　safety　in　subway　system.　This　paper　presents　an　experimental　investigation　with　a　full-scale　hot　smoke　test　to　evaluate　the　performance　smoke　control　system　including　mobile　ventilation　and　smoke　discharge　equipment　in　a　curtain　huge　metro　transfer　station.　Results　showed　that　when　the　smoke　control　fans　were　activated,　the　smoke　raised　up　rapidly　and　formed　an　accumulated　smoke　layer　above　the　net-type　ceiling　and　the　velocity　on　the　stairs　was　not　conformed　to　the　Code　for　Metro　Design.　Moreover,　it　is　also　found　the　mobile　ventilation　and　smoke　discharge　equipment　would　disturb　the　smoke　flow　stability.　Therefore,　the　mobile　system　should　be　selected　as　assistant　equipment　for　the　fixed　smoke　control　system　in　the　metro　station.
