What’s 70-feet long, weighs tons, looks like a 1943 Baldwin 2900 steam locomotive and hangs over the High Line? A Jeff Koons proposed public sculpture and it’s looking for a sponsor. Friends of the High Line are already in love with it and think that a giant steel train monster dangling in the wind from a crane above the former the park’s former train tracks, occasionally spinning its wheels, sounding its horn and blowing steam isn’t scary at all, in fact: “People used to think they’d be uncomfortable with the High Line itself, that visitors would jump off or throw things from it.” Actually, this is awesome. Strung up pathetically over the High Line’s future sleekness, the archaic train will look like a captured beast. It will be like Jurassic Park… for machines. Got $25 million?
