If you feel sick, it's best if you don't get on the train. Help can reach
you much faster if you stay in the station. So, if you feel sick go to the station agent or a police officer - they will help you.
If you become ill when you are on the train, notify the train crew.The train crew has the means to call for medical assistance or the police.
You will not be left alone if you become ill. Someone will stay with you until you are well enough to be on your way or until you are in the right hands. And, during rush hours there are EMTs at various key stations who are ready to help customers who get sick.
Never pull the emergency brake. It will only delay the train and keep help from reaching you.
