Black Diamond Express: This picture was taken at one of the curves on the Lehigh Valley Railroad, along the beautiful Susquehanna River. The train is seen rapidly approaching in the distance, clearly outlined against the grey mountains. Smoke can be seen pouring in volumes from the stack of the locomotive, and as the train approaches closely, she sounds a whistle, warning some section men, who are working on the tracks in the foreground. As she rushes by the camera, the swing motion of the train gives a vivid idea of the lightning speed at which she is traveling. (Edison film catalog)
