Hi Stan, My daughter takes the 113 in the morning at 6:49 She gets it at the train station on North Avenue in Westfield. It has many stops along the way until it gets to the Parkway. Door to door is about an hour. She has been making very good time getting into the city. The later you leave, the more traffic. At night the bus runs about every hour until midnight.
Hope this helps. He you want more information, I will put you in touch with my daughter who takes the bus every day.
NJ Transit posts its schedules online -- for both bus and train. Many in Westfield commute into NYC (both mid-town and downtown). The bus stop is located on North Avenue -- just outside the train station, but it makes stops at other locations. The bus does go through special 'bus lanes' in the Lincoln Tunnel, but, of course bad weather is going to impact the schedule. The bus goes into Port Authority Bus Terminal.
