We were waiting for our train on the platform in the subway. This is one of the cars in the train that passed heading the other way.

Moments later another train came into view.  This one had about 7 cars, each a different color and decorated.  I was informed that it is the "Olympic Train" celebrating the fact of the Olympics being held in Russia this year. I only managed to get pictures of two of the cars.  The pink, yellow and orange cars were very bright!
