Equestrian signalman on the New York Central's Eleventh Avenue freight line circa 1911. In a 1930 article on the West Side tracks' demise, the New York Times wrote of the "eight men and twenty-four horses comprising the famous 'cowboy troop' [or 'West Side Cowboys'] whose function it has been for years to ride ahead of the puffing locomotives as they wheeled along Death Avenue." The dangerous street-level tracks were eventually replaced by a 1½-mile viaduct, the High Line, that after decades of abandonment is being turned into a long, thin elevated park.
