The original station was built a quarter mile to the north and called Scotch Plains station. That station was put in service in 1837 by the Elizabethtown and Somerville Railroad which had completed the line from Elizabethport to Plainfield by that time. Modern-day Midway Avenue occupies the route of the old line. The original line had to skirt the hill at Fanwood because wood-burning locomotives of the time could not climb the steep grade. With the advent of more powerful coal-burning locomotives that were able to climb the Fanwood hill, the Central Railroad of New Jersey (which had taken over the line) began to acquire land in 1867 to relocate the line to its current location. The company's charter from the state required the railroad to acquire all the land between the old line and the new line. The land acquired was fan-shaped. The station name was changed from Scotch Plains to Fanwood Park. Besides a new station, the land was developed by the railroad into suburban housing lots laid out on a network of curved streets and called Fanwood Park. The Central New Jersey Land Improvement Company, a subsidiary of the railroad, built and sold houses in Fanwood Park for the next forty years.
