There was a post somewhere about the customers in the New Haven area, if you wish to find it. I thin it was here, but it could have been on the New Haven H&TS. I lived in Plainville , and my family's company was a customer. There were a few trips where I rode to Cheshire. The clay place used to get IC boxcars. Bozzuto grocery supply, Diamond Lumber, Country Kitchens, Suburban Propane, Forrestville Lumber, and Green's scrap yard were what I remember. I'm sure Pratt and Whitney would have been active before. Plainville had a lumber yard between W. Main and the Broad St. crossings. There was another old warehouse on Whiting St., which might have been a customer at some point. There was an old coal yard in Farmington, just south of the former New Hartford branch junction. Ensign Bickford, in Simsbury was active at one point too.
