Cought, at the right moment.

At Park Royal station in London, I Saw this woman opposite me sitting patiently on a bench waiting for the next train to arrive. While my train was arriving, I instantly thought, but also pre-visualized this exact image, (as my title also indicates). I quickly pre-focused and waited for that instant moment where the train would be inches away from my subject, causing as what we can call a decisive moment.
