A Pennsylvania Railroad I-1sa Decapod-type 2-10-0 freight steam locomotive pushes through a snow-filled cut, likely on the Elmira Branch, en route to coal docks in Sodus Point on Lake Ontario, New York. This image comes from the thousands of cubic feet of records held in MG-286, the Penn Central Railroad Collection, one of the largest and most frequently utilized manuscript groups (non-government-generated collections) at the Pennsylvania State Archives.
