I worked for Dennison Copiers in the late 1960s, early 1970s. We had the Erie-Lackawanna as a customer. I remember going down to the ferry terminal (the offices were on the 2nd floor - close to the river. The copier was often shrouded in fog. Also, they had copiers (all floor models) in many stations. When one required service; they would put it on a caboose, and send it down to Croxton yard; where our serviceman would fix it and E-L would take it back. We had machines come in from as far as Elmira.
