prior to today’s era of containerization, railroad companies maintained large fleets of barges to bring goods between terminals, across and along the hudson river for consumer use, and for shipment overseas. at one time there were over 5,000 non-self-propelled barges. today, however, there is only one surviving example left afloat. the lehigh valley railroad barge #79, built in perth amboy, NJ in 1914, is the only wooden covered barge of its kind left over from ‘the lighterage era’ (1860-1984).  in her 33-year history as a showboat and classroom, hundreds of thousands have come to the waterfront to participate in arts and education programs. see more details of access to the waterfront barge museum here.
