Pacman on trains - new & old

Schlomo in 2007 - via Ekosystem "Eat the Eater " by unknown artist in 2012 via spraycity 
typical train designs include often lines. Lines that remind poeple on playing pac man on trains. The pictures above are two examples that deal with pac man. I remember that i saw more, but i could not find the pictures .... so please continue playing arcade games on trains - I love it !
