"Once an elevated freight railway track, New York's High Line is now an oasis for pedestrians. It has been so popular that other cities are following suit, with plans to replicate the formula in London.

"... In August 1999, local architectural enthusiasts Joshua David and Robert Hammond went along to a public meeting to discuss the future of the High Line.

"Within months the two New Yorkers - variously described as total amateurs and neighbourhood nobodies - founded the Friends of the High Line, a charity that has gone on to transform the abandoned railway line into a wildly successful new kind of public space - part-beach, part-park, and part-promenade."
