Heads up for trains disruptions

Maybe consider hvg 'black box' installed inside MRT, whatever happened, able to retrieve data for investigation. SMRT, can u show the public where is the 'standby ventilation system'? How wld u handle passengers with panic disorder/ anxiety disorders (further worsening their condition - medical compensation for hvg causing distress to them?), physical disability in wheelchair/ leg problem & elderly (expect them to walk such long distance on the railway?)
