1844 The original alignments in Newark and Jersey City.
1866 The Elizabeth Loop Line was already there.
1868 An interesting old alignment (maybe never built) for the Erie Weehawken Branch. Also shows the DL&W before it had its own tunnel.
1874 Both sides of the DL&W before it had its own tunnel. The bridge over the Hackensack was later used by the Newark & Hudson, and part of the S curve on the Boonton Branch was used by the NY&GL connection to the tunnel.
1874 A slightly different Weehawken Branch alignment through Hoboken, plus the New Jersey Junction.
1874 The New York & Fort Lee, including the never-built portion.
1874 The original alignment of the New Jersey RR, plus the Harsimus Branch (which was slightly shortened when the NJRR was straightened).
1891 The Hudson County peninsula, showing only part of the dense network that was later built.
1891 After most of the new routes were built; the old DL&W tunnel approaches are visible.
