      May be just to show that travelling with train in comparison to plane or individual cars is more eco-friendly causing less environmental pollution!

      I don’t know to be honest. I would guess it is the result of bacteria growing in the mucous in your nose, but that really is a guess.

      From: http://www.whyzz.com/why-is-snot-green
      The green or yellow color of snot is usually caused by certain helpers that your body uses to fight off viruses or bacteria. The name for these infection-fighting helpers is “neutrophils,” and it’s the iron in a special enzyme used by the neutrophils to fight off your germs that is usually the source of your snot’s weird, gross color!

      The color of your snot does not necessarily indicate how sick you are – really green snot doesn’t necessarily mean you’re really sick, and clear snot doesn’t necessarily mean you aren’t sick. If your snot is a color that worries you or if you’re just not feeling well, the best thing to do is ask your doctor about it. And remember: It might SNOT be pretty, but your green or yellow snot is probably just a sign that your body is helping you get better quickly!
