The Washington Frederick & Gettysburg Rail Road Engine No. 2 with three passenger cars at the Lake View Casino stop. This is WF&GRR Engine No. 2 is a Forney 0-4-4-T, one of several built new for the New York Elevated Railway and purchased for use on the WF&GRR. The WF&GRR predated the Hagerstown & Frederick Railway and in this photo it is clear that there are none of the electric lines required to power the trolley's the H&F would eventually use on this line.
