Amsterdam has had a metro system since 1977. Currently there are four metro lines, but this will be extended to five lines within the next few years when the infamous North/South line will finally be completed. In the years to come all silver metro trains will be replaced by brand new French trains. Usually we applaud initiatives like these, particularly because the new cars will be fitted with extra wide chairs and all kinds of other modern bells and whistles. On the other hand, it pains us to leave behind all of the 'Metro Art'. In 2008, all of the boring grey trains were decorated with all kinds of artistic scenes. The idea behind it was to prevent the trains from becoming inundated with poor graffiti. Young street artists were given the opportunity to legally spray their creations, graphic designs, photos and drawings on 44 metro cars. The result was a colourful collection of science fiction characters, comic heroes, domestic scenes and satirical works of art. Every time you got on the metro you never knew which piece of mobile art you were about to board. Unfortunately, soon all this will be a thing of the past. If you'd like to try this experience take lines 50, 53 and 54, but don't wait too long.
