The borough is served by the Bound Brook train station, which offers NJ Transit service on the Raritan Valley Line to Newark Penn Station. The historic station building on the north side of the tracks is located at 350 E. Main Street and was constructed in 1913. It is now a restaurant; the other station building on the south side is now privately owned. A pedestrian tunnel connects the south and north sides of the tracks. There are also Conrail tracks going past the station, used for freight trains to and from Newark.
