The Salem Diner is a historic diner at 701⁄2 Loring Avenue in Salem, Massachusetts. It is one of two Sterling Streamliner diners left in Massachusetts, and still stands at its original location. Designated car #4106, it was also one of the last made by the Sterling Company before it closed its doors in 1942. The diner body features a wood frame and porcelain enamel exterior. It has a metal hipped barrel roof, and its eastern end features a characteristic shovel nose. The roofline is decorated by a fin shape that serves as a backdrop for the diner's neon signage. It is mounted on a foundation that is predominantly concrete blocks, with some glass blocks interspersed. Its main entrance is centered on the long side, and is now sheltered by a modern glass vestibule added c. 1960.
