37116 passes Bledlow on 21 April 2013 with the 2C12 13:14 Thame Junction to Chinnor service, during the Chinnor & Princes Risborough Railway's Diesel Gala. The high cloud of an approaching front has just reached the sun, and although the light is not as crisp as just a few minutes before, it would get a whole lot worse during the next five minutes! I had correctly guessed that I might just get the 37 in sun before the Met Office's predicted cloud reached me.
