Following the mid-1860s relocation of the Camden & Amboy rail line from next to the Delaware & Raritan Canal to the present location of the Northeast Corridor, and the subsequent construction of a train station south of the intersection of Washington Road and the new rail line, a community called "Princeton Junction" developed. This community originally featured several farmhouses, a hotel, a general store, a feed mill, and several other businesses centered around the intersection of Station Drive & Washington Road, profiting off of access to other cities provided by the rail line.
