When you stand at the platform masturbating, whilst using endurance to hold the orgasm until a train comes. As the train approaches, simultaneously ejaculate at the window as it goes past. - NOTE: This may be slightly dangerous if you are not an experienced train wanker.
Every weekend I like to stand at the station and furiously train wank.
