The West End Branch train line ran along Sumner Avenue, crossed Tilghman diagonally at 17th Street, then looped back east, at the northeastern end of the Fairgrounds, terminating at 12th and Liberty Streets. The branch allowed this area to become the coal district of Allentown, when city homes were mostly heated by that fuel. In the early 1970's, I photographed Sumner Avenue. Although the coal era was mostly over, some relics still remained. Shown above is a coal sorter at the Morris Wisser Coal Company, at Fulton and Green Streets.
