- Hall_Signal_Company abstract "The Hall Signal Company was an American manufacturer of railway signaling equipment in the 19th and 20th centuries. Hall's equipment was widely used by American railroad companies. The company's founder, Thomas S. Hall, was an inventor who developed several important devices in the history of railway signalling. The company manufactured automatic block signaling systems, disc signals (also called "banjo" signals), a rotating semaphore signal, grade crossing signals, and the first searchlight-style signal.The company was established in 1871 with main offices in New York City and a factory in Meriden, Connecticut.
