Subways need not be boring or dreary! On the contrary, many operators of metros, subways or underground railways want to attract passengers with good station design. This often means extra effort and cost for the metro operators, but it seems to pay off when a metro is more than just a means of transport but something the residents can be proud of.

Stockholm's metro system is referred to as the world's longest art gallery because works of art have been integrated in almost every station since the 1950s. SL spends 10 million SEK per year in safeguarding and developing artwork.
