The Railroads of the Frog War

We think of the Frog War as a local Hopewell thing, and really rather goofy – with cute frog logos for the Elementary School (see earlier post).

But the Frog War was very serious business for the two heavyweight contenders that were fighting to preserve (or break) a monopoly on direct rail service between Philadelphia and New York – the Pennsylvania Railroad and the Philadelphia and Reading Railroad.

The Frog War

The Frog War was the resulting physical battle in January 1876, which saw the massing of several hundred workers just outside of Hopewell with instructions to build (or prevent) the railroad crossing – by laying track, disabling locomotives, constructing blockades, and even crashing locomotives to break though the barriers. With 2000 people on the ground the next morning, the situation was resolved only by the Governor mustering the state militia and a legal ruling from the state Chancellor to allow the track to go through.

The importance of this event was demonstrated by the national coverage in the New York Times – with this front page story on the first day, and a page 2 follow up on the next day, both detailing both the situation on the ground and the legal maneuvering.

The Railroads

And what were the actual local railroads involved in this battle? The Pennsylvania’s proxy railroad was the Mercer and Somerset (M&S), which it constructed with the express purpose of physically blocking the Reading’s proxy, the Delaware and Bound Brook (D&BB).

The Mercer and Somerset was built first, and opened in 1874. It ran from the Delaware River in Ewing through Pennington and Hopewell and curved east to Millstone. The result was not a direct path – the connection to Philadelphia was from Trenton west on the Belvidere Delaware Railroad (Bel-Del) along the Delaware River to Somerset Jct. in Ewing, then northeast on the M&S, and the final connection to New York was through West Millstone.

The Delaware and Bound Brook opened in 1876, after the Reading’s victory in the Frog War. It ran from a Delaware River bridge at Yardley through Pennington, Hopewell, and Belle Mead to Bound Brook.  The full route from Philadelphia to New York then could be one train, but passed over three lines – the new Northern Pennsylvania Railroad from Philadelphia to Yardley, the D&BB to Bound Brook, and then the New Jersey Central Railroad to New York City.

This 1881 Barrington New Railroad Map shows both of the railroad lines through Pennington and Hopewell as of 1879 (before the M&S was shut down). 

The map is annotated to highlight the train lines and stations for the D&BB (blue) and M&S (purple) lines.

The Pennsylvania Railroad lines on the right (marked in red) are the United (now the Amtrak Northeast Corridor) and the Camden and Amboy.

The Pennsylvania RR line on the bottom left along the river (in green) is the Belvidere Delaware (Bel-Del).

More on the Frog War

The “Frog War” is the name of the confrontation that took place on January 5 and 6, 1876 at a railroad crossing just south of Hopewell Borough, as the Delaware & Bound Brook Railroad (D&BB) needed to construct a “frog” so that the tracks of its new line could cross the existing tracks of the Mercer & Somerset Railroad (M&S). After a violent confrontation, the D&BB succeeded, and brought two rail lines across the Hopewell Valley.

More on Hopewell Railroads

Two railroads were built in the 1870s to connect Philadelphia and New York by travelling up from the Delaware River, through Pennington and Hopewell, and then north towards New York. The Mercer and Somerset opened in 1874, but was shut down in 1880. The Delaware and Bound Brook opened in 1876, and is the predecessor of the line that still runs through the area.
