The PB&W also extended its reach into Delaware – on March 15, 1839, it bought the New Castle and Frenchtown Turnpike and Rail Road running from New Castle, Delaware, to Frenchtown, Maryland – but it took 13 years to connect the line to the rest of the PW&B. The "New Castle and Wilmington Railroad" was chartered to do so, and opened in 1852. The line also provided a connection with the Delaware Railroad, which the PW&B took over and began to operate on January 1, 1857. In 1859, the NC&F was abandoned west of Porter, the junction with the Delaware Railroad. By 1866, these moves and others allowed the PW&B to dominate the Delmarva Peninsula rail market.
