Harriman through Monroe and Goshen to Middletown. Service was increased along with the opening of the Secaucus Transfer station in late 2003. 1996 Secaucus collision On February 9, 1996, a Main Line train was involved in a collision with a Bergen County Line train in Secaucus. Service Departing the historic 1907-built Hoboken Terminal, the yards for the coaches to the left, trains pass over two city streets and the Hudson Bergen Light Rail before entering the Bergen Tunnels under the Bergen Hill section of Hudson Palisades. Midway through the tunnel there are air shafts allowing light through and venting out the diesel fumes. Exiting the tunnel, the train curves right onto the Main Line at West End interlocking in Jersey City. Until 1963 this was the DL&W Boonton Branch; about a mile ahead was the connection built circa 1956 with the Erie main line (that after 1963 became the Bergen County Line). Two trains collided head-on here in 1996, killing two engineers and a passenger. The ramps for New Jersey Turnpike Interchange 15X now occupy the Erie alignment-- since the Bergen County line was rerouted adjacent to the Main Line to pass through Secaucus Junction. At Secaucus Junction, all trains stop for passengers to change to and from Northeast Corridor Line, North Jersey Coast Line, Raritan Valley Line and Midtown Direct trains on the Morristown Line, the Gladstone Branch, and the Montclair-Boonton Line on the upper level. The Main Line then runs through an industrial section of Secaucus. Shortly afterwards the Bergen County Line curves right on its new connection to the Erie alignment. The Main Line then crosses over the Hackensack River on the single-track Upper Hack Lift bridge, built in 1958. Double track resumes under the New Jersey Turnpike's western spur after 0.4 mile of single track. The train continues through the Meadowlands and passes the first grade crossing at Valley Brook Avenue in Lyndhurst. The line curves slightly and passes through the 1903 Kingsland tunnel. Kingsland station is shortly after the tunnel in an open cut. Just beyond Kingsland station is Lyndhurst station, on an embankment. After Lyndhurst the train crosses the Passaic River on a swing bridge that has been bolted shut (although it is technically required by Federal regulation to be opened on 24 hours notice). The train passes under Route 3 and approaches Delawanna station. Next stop is Passaic, on an embankment. After Passaic,
