Woodbridge Township's station, locally known as Metropark, also has connections to Amtrak lines. The Northeast Corridor stops at Princeton Junction, which connects to New Jersey Transit's Princeton Branch, the provider of rail service to Princeton University. The line passes through the New Jersey towns of New Brunswick and Hamilton before reaching its southern terminus in Trenton.
