Christmas theme metro train

Have you been lucky to get on the special Christmas train in the Warsaw underground?

The themed train was launched on Dec 6th (St Nicholas day - that is Santa Claus's!) and it will continue until January 6th.
Actually there are two - one at each f two Metro lines.
Both trains can be spotted between 7 am and 8 pm. Apparently it's easier to get on one on M2 line - because the second line is shorter, so statistically... ;-

Personally - I am a happy person who does not travel by metro too often,at least not during the rush hours!
