High Fives / Arrows

Waiting for the MetroLink at Union Station, the doors opened and two gentlemen emerged.  A guy next to me knew them.  They high fived each other and started chatting right in front of the open doors.  People on the train could not get off, and people on the platform could not get on.  Just returning to my hometown, I was immediately happy to see how friendly people were, but saddened to see how poorly they use the train.

St. Louis doesn't have a transit culture, and educating the public takes a lot of work.  Let's begin with these arrows from the MRT system in Sinapore.  When the doors open, the people on the train get off.  After they are gone, the people on the platform board the train.  If you push onto the train when the doors open, you'll trap someone inside.  If you wait for them to get off, then there will be more space for you to board. 

People exiting the train have priority.  People boarding the train should stand out of the way.  When stepping off the train, you should immediately clear the path so others may board.  You cannot linger and chat with your friend.
