Cowboys as cow chasers?
Before the High Line elevated freight trains above the west side streets, there were cowboys on 10th & 11th Avenues shooing carts, vehicles and people off the street bed when the trains rolled by.
The High Line is a section of the former elevated freight railroad of the West Side Line, along the lower west side of Manhattan. It runs from 34th Street near the Javits Convention Center to Gansevoort Street in the Meat Packing District of the West Village. The High Line was built in the early 1930s by the New York Central Railroad and was an active railway until 1980.
