Thank you for your question.
To do this, you would take the subway at the 59th Street station in
Columbus Circle. You can catch any of the trains, the 1, A, D, C, B
or 2, to Penn Station to the PATH train. Once on the PATH, you will
go under the Hudson River (not as exciting as it sounds) and depart in
Hoboken, New Jersey, the first New Jersey stop and just over the river
from Manhattan. There, you will be at the Hoboken train station and
you can catch a train from Hoboken to Spring Valley, New York on the
Pascack Valley Line. The trip on the Pascack Valley train is 33
miles. The Spring Valley station is a five-minute walk from the
address you gave in your question.
An alternate route would be to catch the subway at 59th Street, go to
Penn Station and take the train to Secaucus (buying a trip to Spring
Valley), switch at Secaucus to a New Jersey transit train bound for
Hoboken and then switching at Hoboken to go to Spring Valley.
However, the NJ transit trains aren't going to stop in Secaucus as
much as the PATH is at Penn and it will probably take longer. It is
an option, though.
You could also take the subway to the World Trade Center station and
switch there to the PATH train, then switch in Hoboken for Spring
New York State Rail
