On Tuesday, May 1, 1951, John M. Prophet III brought his wire recorder to New York Central's Interlocking Tower 47; located on the Central's mainline about a mile east of Buffalo Central Terminal. At first glance, the tower seemed like it was built in a spot where it wasn't needed. But when you dig deeper, Tower 47 played a very important role in keeping New York Central's steam engines (and later diesel locomotives) operating in perfect working order. The tower also controlled freight train movements in and out of various New York Central freight yards in the vicinity, including their colossal Frontier Yard, which sadly, is no longer in operation. This is an episode that includes a lot of history along with some great recordings of typical engine and train movements at what was once a very busy location for the New York Central.
