A black and white photograph of two steam locomotives side by side, possibly Pennsylvania Railroad engines, showing the front end of the locomotives. The locomotives appear to be in a railyard.
The Pennsylvania Railroad was established in Pennsylvania in 1846. By the early 1900s it had grown to become the largest railroad in the United States. In 1968 it merged with New York Central Railroad and shortly thereafter filed for bankruptcy, in the aftermath of which the company’s assets were broken up and redistributed through successive corporate restructurings. The Pennsylvania Railroad system serviced Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, new Jersey, New York, Ohio Pennsylvania, Virginia, Washington, DC, and West Virginia.
