On November 16, 1847, Isaac Hopper reflects on a meeting that day with William Barrigan, who was formerly employed on the "Rail Road" at Bordentown, New Jersey. Bordentown's proximity to the Delaware River made it a hotbed for railroad construction. In 1832, the Camden and Amboy Railroad Company opened its first railroad route from Bordentown to Highstown, and by 1839 had managed to connect Bordentown by rail with Trenton and New Brunswick. Competition over Bordentown came from the New Jersey Railroad and Transportation company, but there were enough destinations where both companies could coexist. It is unclear which company William Barrigan worked for, but it is no coincidence that he lost his job in the mid 1840s, as by then the railroad companies had all but completed construction in Bordentown, instead setting their sights on larger cities such as New York and Philadelphia. 

Little information exists on the Bordentown railroad business in the 1840s. Much of what we know gravitates around the 1830s--the decade of its construction and nascency. In the 1870s, the C&A company merged with the NJRR. Interestingly, the NJRR sputtered and died by 1976, portending the incoming epoch of privatization and declension of public goods, including transportation.
