This video showcases the movement of various trains around Tower F in the Black Rock section of Buffalo NY. The controlled trains on the NYC's Niagara Branch as they made their way either to the International Bridge and Canada, or further south into downtown Buffalo. Helping to convey the story of Tower F are the incredible films of William Kessel, one of the founding members of the Niagara Frontier Chapter of the NRHS.
Please note that at approximately 6:05 into the video, I incorrectly identified one of the trains crossing over the International Bridge as a "Canadian Pacific switching engine." Rather, it is an engine of the Canadian National.
