Here's Andy West's former N&W Leslie RS5TRF "Killer" mounted on the north end of the SARM Secret City Scenic Excursion train. We decided to mount the horn "backwards" with the 31/55 bells facing the short hood of the engine, just as it likely would have been mounted on its N&W engine. As N&W/NS started running their trains with the short hood forward, it was very common to hear these horns in this configuration.
