People view Noah's Train at Schaerbeek Station in Brussels, Belgium, March 2, 2019. Noah's Train, a freight train painted with colorful animals, has recently arrived at Belgium's Schaerbeek Station. After departing from the UN Climate Change Conference held in Poland's Katowice in December 2018, Noah's Train made its way through Vienna, Berlin, Paris and its final station, Brussels. At each station, prominent street artists spray-painted two containers with animal motifs, transforming it into the world's longest mobile street artwork ever, with the aim of calling for more climate-friendly freight transport.
