From the finder, "one side is from New York Central & Hudson River Rail Road. The other side says St. John's Park NY."

The New York Central Railroad "(reporting mark NYC) was a railroad primarily operating in the Great Lakes and Mid-Atlantic regions of the United States. The railroad primarily connected greater New York and Boston in the east with Chicago and St. Louis in the Midwest, along with the intermediate cities of Albany, Buffalo, Cleveland, Cincinnati, Detroit, and Syracuse. New York Central was headquartered in New York City's New York Central Building, adjacent to its largest station, Grand Central Terminal.

The Troy and Greenbush Railroad was chartered in 1845 and opened later that year, connecting Troy south to Greenbush (now Rensselaer) on the east side of the Hudson River. The Hudson River Railroad was chartered on May 12, 1846, to extend this line south to New York City; the full line opened on October 3, 1851. Prior to completion, on June 1, it leased the Troy and Greenbush.
Cornelius Vanderbilt obtained control of the Hudson River Railroad in 1864, soon after he bought the parallel New York and Harlem Railroad.
Along the line of the Hudson River Railroad, the West Side Line was built in 1934 in the borough of Manhattan as an elevated bypass of then-abandoned street running trackage on Tenth and Eleventh Avenues. The elevated section has since been abandoned, and the tunnel north of 35th Street is used only by Amtrak trains to New York Penn Station (all other trains use the Spuyten Duyvil and Port Morris Railroad to reach the Harlem Line). The surviving sections of the West Side Line south of 34th Street reopened as the High Line, a linear park built between 2009 and 2014."
